snap.test disconnect [disconnect-OPTIONS] [<snap>:<plug>] [<snap>:<slot>]
The disconnect command disconnects a plug from a slot.

Disconnects the specific plug from the specific slot.
$ snap disconnect <snap>:<slot or plug>
Disconnects everything from the provided plug or slot.
The snap name may be omitted for the core snap.
