How can I re-enable the system notifications, so that they pop up when I'm deleting a Dropbox file?

By mistake, I clicked on 'don't show this again' for the Dropbox popup 'permanently delete this item for everyone' and I want to undo that action. Sometimes this popup save my life

Welcome to our forum, @operacional, and thanks for your post!

Depending on the OS you’re using, you can re-enable these notifications by going to the Account tab of your Dropbox app preferences and pressing the Option/Alt key (on Mac) or the Alt + H keys (on Windows).

Let me know if that helps.
