Axios post request with typescript issue

I am trying to add typescript to my current project, so after using it with Axios post request i am facing an issue.

Usecase is that i want to send "email" "firstname" "lastname" and "password" in my post request and in response i want "accessToken"

Here is the code below

export interface UserRegistrationModel {
  email: string;
  password: string;
  firstname: string;
  lastname: string;
}



export const register = async (user: UserRegistrationModel) => {
  const { data } = await http.post<UserRegistrationModel>("/users", user);
  return data;
};

This is my function called after i submit the registration form like

register(values)
        .then((data) => {
          console.log(data.accessToken);
          setLoading(false);

        })
        .catch(() => {
          setLoading(false);

        });

so here in my then block when i try to access "accessToken" by data.acessToken is throws error

Property 'accessToken' does not exist on type 'UserRegistrationModel

so i tried to define a new Interface named "AuthModel" but then when i assign it to data like

export interface AuthModel {
  accessToken: string
}


 register(values)
        .then((data:AuthModel) => {
          console.log(data.accessToken);
          setLoading(false);
        })
        .catch(() => {
          setLoading(false);
          setSubmitting(false);
          setStatus("Registration process has broken");
        });

it says

Argument of type '(data: AuthModel) => void' is not assignable to parameter of type '(value: UserRegistrationModel) => void | PromiseLike'. Types of parameters 'data' and 'value' are incompatible. Property 'accessToken' is missing in type 'UserRegistrationModel' but required in type 'AuthModel'.

Below is the axios config in anyone wants to see

// http.ts

import axios, { AxiosInstance, AxiosRequestConfig, AxiosResponse } from "axios";

enum StatusCode {
  Unauthorized = 401,
  Forbidden = 403,
  TooManyRequests = 429,
  InternalServerError = 500,
}

const headers: Readonly<Record<string, string | boolean>> = {
  Accept: "application/json",
  "Content-Type": "application/json; charset=utf-8",
  "Access-Control-Allow-Credentials": true,
  "X-Requested-With": "XMLHttpRequest",
};

// We can use the following function to inject the JWT token through an interceptor
// We get the `accessToken` from the localStorage that we set when we authenticate
const injectToken = (config: AxiosRequestConfig): AxiosRequestConfig => {
  try {
    const token = localStorage.getItem("accessToken");

    if (token != null) {
      config.headers.Authorization = `Bearer ${token}`;
    }
    return config;
  } catch (error: any) {
    throw new Error(error);
  }
};

class Http {
  private instance: AxiosInstance | null = null;

  private get http(): AxiosInstance {
    return this.instance != null ? this.instance : this.initHttp();
  }

  initHttp() {
    const http = axios.create({
      baseURL: "https://api.example.com",
      headers,
      withCredentials: true,
    });

    http.interceptors.request.use(injectToken, (error) =>
      Promise.reject(error)
    );

    http.interceptors.response.use(
      (response) => response,
      (error) => {
        const { response } = error;
        return this.handleError(response);
      }
    );

    this.instance = http;
    return http;
  }

  request<T = any, R = AxiosResponse<T>>(
    config: AxiosRequestConfig
  ): Promise<R> {
    return this.http.request(config);
  }

  get<T = any, R = AxiosResponse<T>>(
    url: string,
    config?: AxiosRequestConfig
  ): Promise<R> {
    return this.http.get<T, R>(url, config);
  }

  post<T = any, R = AxiosResponse<T>>(
    url: string,
    data?: T,
    config?: AxiosRequestConfig
  ): Promise<R> {
    return this.http.post<T, R>(url, data, config);
  }

  put<T = any, R = AxiosResponse<T>>(
    url: string,
    data?: T,
    config?: AxiosRequestConfig
  ): Promise<R> {
    return this.http.put<T, R>(url, data, config);
  }

  delete<T = any, R = AxiosResponse<T>>(
    url: string,
    config?: AxiosRequestConfig
  ): Promise<R> {
    return this.http.delete<T, R>(url, config);
  }

  // Handle global app errors
  // We can handle generic app errors depending on the status code
  private handleError(error: any) {
    const { status } = error;

    switch (status) {
      case StatusCode.InternalServerError: {
        // Handle InternalServerError
        break;
      }
      case StatusCode.Forbidden: {
        // Handle Forbidden
        break;
      }
      case StatusCode.Unauthorized: {
        // Handle Unauthorized
        break;
      }
      case StatusCode.TooManyRequests: {
        // Handle TooManyRequests
        break;
      }
    }

    return Promise.reject(error);
  }
}

export const http = new Http();
