share floodlight wired

I have a floodlight wired that activates 2 cameras. The cameras are shared but I can not get the floodlight shared. In other words I get notifications when the floodlight is activated but shared users don't. I can not find any documentation on how to share the floodlight so other users get the activation notification. The app tells me it can't share grouped devices but there is no choice except to create a group when setting up the floodlight. Any help is appreciated. TIA
