### Steps to reproduce

1. Select a shared file
2. Try to delete this file: it shows "Leave this share" instead of deleting

It is unclear what "Leaving this share" means. It is semantically different from deleting a file.

### Expected behaviour

I want to delete a shared file.

It does in fact delete the file but it's not clear from the text, if this is intentional.
