How to use a RecyclerView inside TextInputLayout of MaterialDesign?

Question

This is a screenshot from an Android app from the play store. I am trying to replicate the design of this screen. I used TextInputLayout from Material Design to create the input boxes. But I am unable to replicate the colour section in the above screenshot. I have figured out that they are using Recycler view inside TextInputLayout. I tried it, but it only shows the colours list without the box.

Here is the code that I have used-

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout

android:layout_width="match_parent"
android:layout_height="match_parent"

tools:layout_marginRight="16dp"

    app:hintTextColor="@color/label_color"
    app:helperTextEnabled="true"
    android:layout_marginTop="16dp"
    app:layout_constraintTop_toTopOf="parent"
    app:helperText="@string/helper_text_counter"

    <com.google.android.material.textfield.TextInputEditText
        android:id="@+id/etName"
