Simple iOS Trackpad

Hi, I am loving BTT so far but have an issue I'd love to solve.

Basically I want to use my iPad as a large trackpad to control the viewing of a 360 degree video (see mp4 linked here)

The only controls I need are drag (x and y) and pinch to zoom.

By default the pinch to zoom is somewhat working but the cursor move is just a move motion and not a drag.

Any ideas how I can make this work?

Thanks
Phil

BTT Remote allows double tap to drag
