Porting from SQLite to PostgreSQL: What is according of datatype byte[] and DateTime in .NET 6 inside PostgreSQL 14.5 SQL DDL script?

My context: I need creating an web-app use ASP.NET Core WebAPI .NET 6, Entity Framework Core 6, PostgreSQL 14.5 with JWT authentication/authorization. I mimics a sample at https://github.com/patrickgod/AuthenticationWebApi , then fork to me https://github.com/donhuvy/AuthenticationWebApi .

This source code use .NET 6 , SQLite , Entity Framework Core 6, HMACSHA512 :

namespace AuthenticationWebApi.Models

{
    public class User
    {
        public int Id { get; set; }
        public string Username { get; set; } = string.Empty;
        public byte[] PasswordHash { get; set; } = new byte[32]; // <-- In don't know how to choose according datatype in PostgreSQL' DDL script.
        public byte[] PasswordSalt { get; set; } = new byte[32]; // <-- In don't know how to choose according datatype in PostgreSQL' DDL script.
        public string RefreshToken { get; set; } = string.Empty;
        public DateTime TokenCreated { get; set; } // <-- In don't know how to choose according datatype in PostgreSQL' DDL script.
        public DateTime TokenExpires { get; set; } // <-- In don't know how to choose according datatype in PostgreSQL' DDL script.
        public string Role { get; set; } = string.Empty;
    }
}

I need migration to PostgreSQL 14.6 . My wrong SQL script is

CREATE TABLE public."my_user"
(
    id integer,
    username character varying(32),
    password_hash character varying(32), // <-- Incorrect mapping.
    password_salt character varying(32), // <-- Incorrect mapping.
    refresh_token character varying(32),
    token_created time with time zone, // <-- Incorrect mapping.
    token_expires time with time zone, // <-- Incorrect mapping.
    role text
);

ALTER TABLE IF EXISTS public."my_user"
    OWNER to postgres;

I use table name my_user for avoiding duplicate with reserved keyword user in PostgreSQL database system.

Help me mapping correct datatype for SQL script inside PostgreSQL. I hope you understand my need (you can ask me for clarification).
