If you want to remove your project from this studio but don't know how, go to this tutorial: https://scratch.mit.edu/projects/67001118/
(PS: To decline a studio invitation, use your human ability to ignore.)
Try not to add a project that clearly states in the description that the creator doesn't want their project in an AE studio.
Feel free to request to be a curator or moderator.
