channels.getAdminLog can be used to list recent admin activity.
A channelAdminLogEventsFilter can be used to filter out actions of a certain type, and the admins field can be used to show only actions by certain admins.
q can also be used to filter only logs matching a query string.
See the type page ยป for the full list of available events.
