Do ıt have Room.IsOpen Listener

I change room properties

Room.IsOpen=false;

But ı did not found ant trigger for complete room close.

I've tried Room.IsOpen=close While there is no internet connection.

print(Room.IsOpen);
Result=> false;

Is there a method that tells you that room properties have changed.
OnPhotonCustomRoomPropertiesChanged Does not give results for IsOpen=false.
