More straightforward image sharing

One of my primary usecases with NextCloud is project screenshot sharing. Basically I would like to take a screenshot to clipboard, directly paste it into browser and just copy share link back to clipboard. (Imgur does this pretty neatly, but I would like to keep the data on our own server)

Currently the procedure involves saving screenshot to a disk, uploading it, clicking open the share menu, creating share link.

Could this functionality be added with an app?
