How to allow an app to take screenshots automatically?

How can I allow an app to automatically take screenshot? I'm not talking about apps disabling screenshots on them, I can take screenshot of the thing manually, but I'd like to automate it. I use the app Automate, which has a screenshot action, but when I run it, a dialog appears asking me if I want to allow the app to see everything what is on screen, and that happens every time. I basically want to autoapprove this dialog. Is there a way to do that? Thanks
