Touch Controller input while Rift S is on Desk

I'm working on an unreal engine project with the Rift S. I have setup UE_LOG output to display in the unreal engine output log panel if I click buttons on the touch controllers. Everything works if I am wearing the Rift S.

But if I take off the device and put it on my desk. The display in the device automatically turns off even though I can see the device is still tracking properly in the VR Preview of the editor. The touch controllers track properly in this state but the buttons stop responding. I would like to be able to leave the device on my desk and have the touch controllers report button clicks so i can see the various editor windows during development.

How can I achieve this?
