Contact people shared in a workspace

It would be useful to be able to contact all users who a workspace has been shared with. Either via a send email button in workspace or an ability to extract the email addresses of those shared.

From time to time we need to contact people to see if they are still using the workspace/dashboard we set up for them. It's currently difficult to get all the email addresses of the users. It is a manual process of seeinbg who it is shared with then manually extracting each individual email. This is very time consuming when shared with a large prportion of the office.
