Collab Viewer Template Input change

i’m using the Collab Viewer Template and i want to change the basic looking around input.
Now you need to press and hold down the right mous button but i want to look around like in the first person template where you don’t need to press any mouse button.
i’m trying to figure out how to disable it in the template, but i can’t find where the right mous button is used for the camera input.
Even if i bypass the boolean check on every pawn the camera doesn’t move without pressing the right mouse button.
Any ideas?
