Not OP but VSCode has a plugin called Live Sharing that allows remote collaboration on a workspace, with independent cursors, navigation, files opened, etc. It's fantastic, honestly, and it's one of the few things that'll prompt me to open vsc over emacs when the need arises. I believe OP is asking whether there is an emacs package allowing interop with it so his pair can use vsc and her can continue to work in emacs.
