Panel only view
In the Settings --> Organization page, scroll down to settings, then check the "Enable Panel Only View" option, and click save. That will make it so all "Clinician" role users see only patients assigned to them in their patient list, tasks that either have no patient or patients assigned to them (i.e. filtering out tasks with patients not assigned to them), and appointments for patients assigned to them.
This is a clinic-wide setting which means it is only set up an admin, not each individual clinician. There will be an "All patients" filter at the bottom left of the navbar that will be available for clinicians to toggle in case they need to see other patients.
After enabling this setting, each clinician will need to refresh Akute in order to get the updated settings.
