Use record-based security to control access to records (Developer Guide for Dynamics 365 Customer Engagement) | Microsoft Docs

Based on the current design, when the user was assigned share access for this record, he can remove and modify other user's privileges on this record.

For example,

user A and Team A assigned all access for a record. Later user A can modify and evenly remove Team A all access.

We need to limit this right, which when a user was assigned share access, he can only modify himself or he has shared the user.
