How to show the progress in the percentage of getting a Response in Retrofit?

Question

Occasionally getting the Response in JSON format can take a few minutes because the JSON can have multiple objects in it.

My goal is to show the progress of getting the Response.

For this purpose I simplify my example of getting the Response using Retrofit.

UserApi

@GET("users")
    @Headers(
        "Accept:$HEADERS_ACCEPT", "Content-Type:$HEADERS_CONTENT_TYPE",
        "Authorization: $AUTHORISATION_TYPE $API_KEY"
    )
    fun getUsersList(@Query("page") pageNo: String, @Query("per_page") perPageNo: String): Call<List<User>>

Repository:

 override suspend fun getUsersList(pageNo: String , perPageNo: String,
                                      usersLiveData: MutableLiveData<List<User>?>) = withContext(ioDispatcher) {

        val call = retrofitUserApiInstance.getUsersList(pageNo, perPageNo)

        call.enqueue(object : Callback<List<User>> {
            override fun onFailure(call: Call<List<User>>, t: Throwable) {
                usersLiveData.postValue(null)
            }

            override fun onResponse(call: Call<List<User>>, response: Response<List<User>>) {
                if (response.isSuccessful) {
                    usersLiveData.postValue(response.body())
                } else {
                    usersLiveData.postValue(null)
                }
            }
        })
    }
