Watching private Vimeo videos

Hi there! I need to watch an unlisted Vimeo (with link video together. But when I put a link to the video, watch2gether says “nothing is found”. Is there any opportunity to watch this kind of videos?

The only workaround I’ve found is to change the Video’s privacy settings on Vimeo to allow anyone to watch. Then change it back to private after we’re done.
