 Power levels required for sending specific event types, in the form {"m.room.whatever0": 60, "m.room.whatever2": None}. Overrides events_default and state_default for the specified events. A level of None causes the target event to revert to the default level as specified by events_default or state_default. **kwargs: Key/value pairs specifying the power levels required for various actions: - events_default(int):
