Problem getting OpenXR input for Vive controller menu button.

Using Input Actions I have been unable to get input from the Vive controller menu button (hamburger icon).

These are the bindings I have tried:

Unity 2020.3.4f1
OpenXR Plugin 1.2.0

Looks like this is a bug with SteamVR, fixed in a patch 2 months ago but still in beta: SteamVR - SteamVR Beta Updated - 1.17.1 - Steam News
