NodeJS, Mongoose prevent Push to write if same data is already in the array

I have app where I have Users. Every user can be an owner of an item or multiple items..

If user is already owner of that item prevent to push the item object into array, if already exists.

I already tried different solutions (I will write what I tried in the end of the question).

User model:

import * as mongoose from "mongoose";
const Schema = mongoose.Schema;

const UserSchema = new mongoose.Schema({
  email: { type: String, required: true, min: 6, max: 255 },
  password: { type: String, required: true, min: 4, max: 1024 },
  role: { type: String, required: true, default: "User" },
  owners: [
    {
      type: Schema.Types.ObjectId,
      ref: "Owners",
      required: false,
    },
  ],
});

module.exports = mongoose.model("Users", UserSchema);

Add owner to user controller:

exports.addOwnerToUser = async (req: Request, res: Response) => {
  try {
    console.log("here");
    let ObjectID = require("mongodb").ObjectID;
    const mongoose = require("mongoose");

    const user = {
      email: req.body.email,
      ownerId: req.body.ownerId,
    };
  
    const updatedUser = await User.findOneAndUpdate(
      {
        _id: req.params.userId,
        owners: { $ne: req.body.ownerId },
      },
      {
        $push: { owners: req.body.ownerId },
      }
    );
  

    res.status(201).json({ sucess: true, msg: "User updated sucessfully" });
  } catch (err) {
    res.status(404).json(err);
  }
};

I already tried solutions like this, but nothing works as expected.. (check the commented code)

exports.addOwnerToUser = async (req: Request, res: Response) => {
  try {
    console.log("here");
    let ObjectID = require("mongodb").ObjectID;
    const mongoose = require("mongoose");

    // add get user and find if he already has this id.. if has then json 200
    // if not i execute line 230

    const user = {
      email: req.body.email,
      ownerId: req.body.ownerId,
    };
    /*  const updatedUser = await User.findOneAndUpdate(
      { _id: req.params.userId },
      {
        "ownerId.ownerId": {
          $ne: ObjectID(req.body.ownerId),
        },
      },
      {
        $addToSet: {
          "ownerId.ownerId": ObjectID(req.body.ownerId),
        },
      },
      {
        new: true,
      }
    ); */

    const updatedUser = await User.findOneAndUpdate(
      /*       {
        _id: req.params.userId,
      },
      {
        $addToSet: {
          owners: req.body.ownerId,
        },
      },
      {
        new: true,
      } */
      {
        _id: req.params.userId,
        owners: { $ne: req.body.ownerId },
      },
      {
        $push: { owners: { ownerId: req.body.ownerId } },
      }
    );
    console.log(updatedUser);

    /*  const updatedUser = await User.findOneAndUpdate(
      { _id: req.params.userId },
      {
        $push: { ownerId: { ownerId: req.body.ownerId } },
      }
    );
    console.log(updatedUser); */
    //     $addToSet: { members: { name: 'something', username: 'something' } }

    /*
     User.findByIdAndUpdate(req.params.user_id,{$set:req.body},{new:true}, function(err, result){
        if(err){
            console.log(err);
        }
        console.log("RESULT: " + result);
        res.send('Done')
    });
};
*/

    res.status(201).json({ sucess: true, msg: "User updated sucessfully" });
  } catch (err) {
    res.status(404).json(err);
  }
};
