Civi 5.42 D7
I have set up a case system for our organisation to allow "Volunteer Counsellors" to access civi, see the clients they are allocated to and manage their clients' cases.
The "Volunteer Counsellor" role does not have the blanket view all contacts permissions in civi. I've set up the Counsellor of/ Counsellor is relationship to be permissioned so that the counsellor can see/ edit/manage the details of the client. The Counsellor of/is role is also the Case Manager role in the case. I've set up Drupal ACLs so that the counsellor has access to specific groups of contacts which includes other Service Staff who may interact with the client.
As a counsellor I can log in, find my client in Civi and see activities in the activity tab and view/ edit those added by members of service staff. And tbh, that's what I expect.
Once these activities are "filed on case" by an administrator, they are not visible to the counsellor in the case listing. Although they are visible to those with staff/ admin roles.
I can make these activities visible to the counsellor by adding them as activity assignees.
But I had thought that the permissions for the volunteer counsellor role to be able to see activities in the activity tab, would be sufficient for them to see the same case activity listing.
Is this a known feature? Have I overlooked something
