Using FLIR/TV camera on planes (scientific research)

Hello,
I noticed there is a nice TV/FLIR screen on the Optima plane (scientific research version) to the right of the cockpit. I can manage to change the contrast and switch between functionalities (FLIR or day TV), but I cannot find any controls to steer or zoom/unzoom it. The same issue occurs on the DA-62 scientific research version.
Is there a hidden function somewhere?

Thanks
