How to override TalkBack announcement for SearchView

My app has a SearchView component implemented in the menu bar like this:

<item
    android:id="@+id/global_tx_list_toolbar_search"
    android:icon="@drawable/ic_search_mag_glass_24dp"
    android:title="Search"
    app:actionViewClass="androidx.appcompat.widget.SearchView"
    app:showAsAction="collapseActionView|always" />

With TalkBack on, when I click the search icon and the SearchView widget opens, it announces "Space, edit box, ...".

I would like it to announce "Search, edit box, ..."

How can I do this? I cannot reference the internal EditText easily (its an internal implementation so not sure i should).
