If you’re the owner of a shared spreadsheet with access set to “Only invited people,” or if the owner gave you permission to invite others, you can change access or permission for all participants.
Go to the Numbers app on your Mac.
In a shared spreadsheet, click in the toolbar, then click Manage Shared Spreadsheet.
Do any of the following:
To change who can access the spreadsheet, choose one of the following:
Only people you invite: The original link no longer works for anyone. Only people who receive an invitation from you and who sign in to their Apple Account can access the spreadsheet.
Anyone with the link: People you originally invited can still open the spreadsheet, along with anyone else who has the link. They don’t need to sign in with the email address or phone number you used to send the link.
To change who can make changes to the spreadsheet, choose one of the following:
Can make changes: People can edit the shared spreadsheet.
Can view only: People can view the shared spreadsheet but not edit it. They can’t reply to or delete comments in the activity list, and when they join a spreadsheet, no notifications appear.
To give all participants permission to invite others to share the spreadsheet, select the “Anyone can add more people” checkbox.
Click Done.
