Cannot Tag a Guest in a zoom Doc

It's not possible to tag a guest in a Zoom doc comment, which basically means you can't use a guest; otherwise, you have to write them an email to say "hey, i tagged you" which is pretty pointless then having guests in docs

It only allows tagging team members.

Settings do not change anything. I've checked all settings within the Docs workspace.

Does anyone else have this issue with Zoom any expected resolution for that
