The HoloLens 2 voice commands, "Bigger", "Smaller", and "Face Me" all work perfectly for Slate applications which are opened within the immersive Remote Assist application.

However, same above voice commands do not work for the Remote Assist Call Window, nor a Screen Sharing window.

The reason why this is important is because some technicians are not entirely familiar with the "pinching and stretching" with their hands yet, and it would be much easier to instruct them to say, "Look at the Screen Sharing window and say, 'Face Me' and then 'Bigger'" so that they can see the screen sharing window better.

By default, the screen sharing window opens in a weird spot, to the right side of the Remote Assist call window and half-hidden by the call window,. and most of the time, screen share starts off facing downwards instead of straight at the technician. Technicians have stated that this is hard to read at first, until they have grabbed and changed the default screen share window location.

tl;dr: If we can use the Slate Voice commands on the screen share window, it will help navigate the Remote assist interface better without using our hands.
