Restrict technician's access to see all reports in mobile app

Hello guys,

we have created some reports and a few of them are for technicians, so they should be seen in the mobile app. But technicians should not be allowed to see all reports including financial staff and so on. How can we restrict their access to these reports? Or from the other end, how can we give them access only to their reports?

We were hoping to create some OWN conditions in Permissions but it doesn't look like it is possible.

Do you have some solution, please?

Thank you very much.
