1. Create a List View.
2. In the filter select “My case teams”.
My case teams will pull cases that you are part via Case Team. Even if you are the owner of Case record, it won’t pull. You should be added as part of Case Team to pull while using My case teams filter.
If the Admin User uses the list view with My case teams as the filter, then this Test 1 Case will be displayed as the Admin User is added to Case Team as an Auditor.
