Creating a looming visual that retracts

[professionalflyswatter]

Hi I am currently working on a looming visual that needs to return back to the original state of a small circle after expanding to covering the whole screen. I am quite new to Bonsai so i am still unsure about how to implement this. This is my current workflow:

Furthermore, I have this workflow atm for the triggering of the visual using 2 cameras but now the visual keeps triggering multiple times if an object is seen in stead of just once. Is there a way to create a period in which triggering is canceled?
