Using Overlay keyboard on Vive Focus 3

[Dynepic]

The Quest uses an Android Manifest setting to enable the overlay keyboard:

 <uses-feature android:name="oculus.software.overlay_keyboard" android:required="false"/>

Is there an equivalent setting for the Vive Focus 3?  Does it require some other OpenXR setting?  Like composition layer?

Did you ever manage to find an answer for this? I've been trying but it doesn't matter if I use wave or openxr, I just can't work out how to get the keyboard to show up when a text field is selected. It seems like such basic functionality yet I can't see any answers to this question.
