How to delete e2e directory

I installed e2ee and it worked fine. I made some test folders to test the functionality before adding “real” files. However, now that I want to clean up my dir tree, I cannot figure out how to delete my e2e test folders. Please tell me how this is done. Thanks.

Any updates on this topic?
I have the same question.
