How do I find Trash Can in MN 4 app?

In MN 4 app, how can I find the Trash Can to delete its contents? I recently deleted a bunch of study sets, but my MN storage size didn’t reduce on iPad, so I assume a Trash Can needs to be emptied. But I can’t find it. Thanks.

Hello

currently uses the repository to replace the Recycle Bin, and you can delete historical versions in the repository.
