default UI select button not working with OpenVR plugin

[lashmanRB]

when using the built-in XR plugins (for WMR and Oculus) - i can just use the built-in XR rigs with Unity's UI system no problem .. but when i switch to the OpenVR plugin suddenly i can no longer select anything in the UI ... i can still see the line rendering ray, the buttons still get highlighted when i hover over them, but when i press the trigger (or any other button) - nothing happens

this happens on WMR, Vive, and even Index

(i should probably add that i'm using HDRP ... but again, it works just fine when using the build-in WMR and Oculus plugins, only breaks using this one)

Input is not supported through Unity's XR API. You'll need the SteamVR Unity Plugin for that. See this thread for more information: #16
