How set scroll to bottom in recyclerview

Question

Tell me, what could be the problem? I'm creating a chat, and my recycleriew will scroll up by itself if there is any asynchronous loading of content. For example, I upload an image using the coil library and after downloading it, the list will scroll up by about half of the imageview. If you remove asynchronous loading, then everything works as it should

My recyclerView in xml:

  <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/messagesList"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_gravity="center_horizontal"
            android:orientation="vertical"
            app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
            app:layout_constraintBottom_toTopOf="@id/inputPanel"
            app:layout_constraintTop_toBottomOf="@id/conferencePanel"
            android:clipToPadding="false"
            tools:listitem="@layout/item_custom_outcoming_text_messages" />
