* support: internally, we have both "midi" and "midi-sysex" permission types
* but we only have a "midi" (public) permission name.

* Note: the `MidiPermissionDescriptor` descriptor has an optional `sysex`
* boolean, which is used to determine whether to return "midi" or
* "midi-sysex" for the MIDI permission.
