Change or revoke somebody's access

1. Open People & access and find the person under “In this organization”.
2. Press “Change access”, choose a new answer to “What is this person here to do?”, and read what they gain and lose.
3. Press “Save access”.

“See it the way they will” shows the screens they will be offered, read-only.

“Revoke access” removes them from the workspace; their history stays. “Let them back in” restores it. Choosing “No access” for somebody who has access is also a revocation.
