swift - How may participants reverse their acceptance of CKShare?

Question

Is there a way to implement the behaviour - participants reverse their acceptances of CKShares? After the participants accept the CKShares, they go over the shared and say oh no I don't want to contribute anything to the shared and I don't even want to keep the shared records in watch lists of their UI interface.

How do we do to remove them from such collaborations (from shared database to be exact)? The use case is very legitimate as people may accept somethings so that having a chance to go over a bit before decide wether they actually contribute their time and efforts into the shared.

I have tried to use CKModifyRecordZonesOperation to delete the shared zone of CloudKit shared database:

var zoneOp = CKModifyRecordZonesOperation(recordZonesToSave: nil, recordZoneIDsToDelete: [zoneID]

zoneOp.database = sharedDB

However, it seems any shared zones can't be deleted from any participants' iOS devices (except for using their development CloudKit Dashboards that may work though) as such attempt is followed by CKError - disallow delete zone...
