Creates a custom role with the specified permissions.

Caution: You must include the toggle privilege for an application alongside any other privilege for that application. For example, to assign WAS.SCAN_WAS.READ, you must also assign WAS.TOGGLE_WAS.USE. If you omit it, the request fails with a 400 response and an Invalid role_permission_string error. Where a category within an application has its own toggle privilege, such as VM.VM_SCAN.TOGGLE_VM_SCAN.USE, you do not need to assign it: Tenable adds it for you.
