How do I set UICloudSharingController.availablePermissions to not allow participants other than the owner of CKShare to copy or send a link from UICloudSharingController?

I have an app that uses CKShare and UICloudSharingController to share data with other users of my app. I noticed that when Owner shares with UserA, UserA is able to "copy" the link or "send" the link, as the title of the button use. How do I disable that completely so that only the owner can copy or send the link? Also, what determines whether it says "Copy Link" or "Send Link"? Does that have to do with the version of iOS?

I've tried every combination of UICloudSharingController.PermissionOptions to set to UICloudSharingController..availablePermissions ... [.allowPrivate, .allowReadOnly], [.allowReadOnly], [.allowPrivate], and []. Setting the value to [] sets it to .standard, which does the exact same thing as [.allowPrivate, .allowReadOnly], though the value is different for availablePermissions property.

fwiw having the share link in and of itself doesn't give any access to the root record or zone being shared.

I figured out what's confusing me. With the latest iOS (16.1.2), UICloudSharingController doesn't restrict who can have access to the share when I set the availablePermissions to include .allowReadOnly and exclude .allowReadWrite. I need to post a different question to ask that.
