Help with adding interactivity to lens

Hi all,

I presume this current issue will require scripting to fix so I will put this here.

I am lookin for a way to add various functions to a single lens which are triggerable in some way in snap camera. This would typically be making a layer visible or invisible etc.

Logically I would have thought this would be done with hotkeys, but as far as I can tell there is only a single hotkey function in lens studio - So i am unsure how to approach doing several different effects separately and triggering them separately.

Many thanks.
