Deleting attachments?

@fynhv
Hi there 😀
For Photos - you can upload Photos, edit them and delete them.
When it comes to attachments you can upload and link them, but I didn't found a way to delete an uploaded attachment. Neither in Frio, nor in Vier.
Also I can't find a way to list the my uploaded attachments

Is there a way to list and delete attachments that I have just overlooked?
