If you’re the owner of a document whose access is set to “Only invited people,” or if the owner of a shared document gives you permission to add people, you can invite more people to join the document using their Apple Account.
Go to the Pages app
on your Mac.
Do one of the following:
Choose File > Manage Shared Document (from the File menu at the top of your screen).
Click
in the toolbar, then click Manage Shared Document.
In iCloud Drive, Control-click the file, then choose Manage Shared Document.
Click Share With More People, then choose a method for sending the invitation to collaborate:
Mail or Messages: Type an email address or phone number for each recipient, add a note if you want, then click Send (for Mail) or press Enter (for Messages). A link to the file is sent to each recipient.
Notes: To share a link to the file in the Notes app, select or type the name of the recipients, click Share Link, choose the note where you want to save it (or create a new one), add text if you want, then click Save.
Invite with Link: Copy the file’s link, so you can send it or post it using any internet service that’s already set up on your Mac. Type an email address or phone number for each recipient, then click Copy Link. Open the app you want to use to share the link, click where you want to paste the link, then choose Edit > Paste (from the Edit menu at the top of your screen), or press Command-V on the keyboard.
Click Done.
Note: The link may appear in the body of the message as a stylized graphic with the document title—be sure not to edit or delete it.
Any participant can copy a link to a document and paste it somewhere else—for example, to save the link where they can easily access it. If the owner limited access to people they invite, the link only works for invited participants.
You can change the sharing settings for the new people after you send the link.
