"On Preview Mouse Button Down" via Widget Interaction on Quest not working (Works on Windows)

Hello, I am wondering if anyone knows of a way to make OnPreviewMouseButtonDown override functions work on Oculus Quest / Android?

I am using it specifically to spawn a keyboard if the selected field is a text box, and it works on Windows in VR preview, however on Quest (Android), same project, I can see that OnPreviewMouseButtonDown is not firing.

Any ideas?

Thank you,

-Brandon!
