Please ensure your feature request is not already on the roadmap or associated with an issue. This can be checked here.

Is your feature request related to a problem? Please describe. Analyst or other regular user is not supposed to have delete capabilities on cases/tickets and tasks Only administrators should have access for deletion This is to make sure all our cases and tasks is properly audited since once a case and task is deleted it will never be recovered (and this is very critical)

Describe the solution you'd like Add "case_delete" and "task_delete" permission under access
