What is the correct way to enter an Array?

Question

I want to enter data via Postman into an array form using id Collection in the database also how can I write a valid JSON script for the modal for the modal

Add data using id Collection controller

const addAcademicExperience = async (req, res, next) => {
    //const id = req.params.id;
    const {AcademicExperience} = req.body;
    let academicexperience;
    try {
        academicexperience = await AcademicExperience.findByIdAndadd(id, {
            AcademicExperience
        });
        await academicexperience.save();
    } catch (err) {
        console.log(err);
    }

    if (!academicexperience) {
        return res.status(404).json({ message: 'Unable to Add' })
    }
    return res.status(200).json({academicexperience});

model Schema Some data is required in an array and some are not

per user per user

To clarify, the site is similar to LinkedIn

const mongoose = require("mongoose");

const Schema = mongoose.Schema;

const FacultySchema = new Schema({
  Faculty_ID: {
