How to give app access to camera

[Lufbrarunner]

I have written a python program for face and object detection. When I try to run this program from Thonny (a python IDE) I get an error that says there is no permission to access the camera. If I go to Security & Privacy to allow access there seems to be no way to add Thonny to the list. When I tried with VSCode it asked for permission to access the camera and was added to the list. I am also able to run the program from a terminal with no problem. Although I am able to use the program by other means, I would like to use Thonny, as it is better when setting up virtual environments. As ever any ideas would be welcomed.
