As the Owner of the majority of the Workspaces in our company, I often receive the email from an external party, requesting access to a particular sheet(s). Whilst I may be the Owner, I am not typically the manager of the project and have little insight into what role that external party plays.
On receipt of these requests, I then need to search the system and/or do a ring-around to our team to find out where it may have come from.
If the Request included a little bit more information - ideally the name of the Workspace the Sheet is stored - it would save substantial time. We use some very generic Sheet names making identification difficult sometimes.
