Send Data from an Activity to the Fragment using Firebase

I'm developing an App that in the first Activity has a RecyclerView with the names of the Patients saved in Firebase. Through the addOnItemTouchListener and onclick I can identify which patient is selected, after selecting the Patient I must pass the identifier to a Fragment that will have all the patient data.

With this identifier I make a new query in Firebase to list the data of this selected patient.

I'm using Parcelable to do the communication, but it's not working, the result inside the Fragment is always null. Follow the fuck, if anyone can help me.

Patient Class with Parcelable Class:

    package com.fisioapp.rodiney.classes;

import android.os.Parcelable;

import com.fisioapp.rodiney.config.ConfiguracaoFirebase;

import com.google.firebase.auth.FirebaseAuth;
