Ring Spotlight Cam Plus, Plug-in

I've got several Ring products and I'm interested in getting the Ring Spotlight Cam Plus Plug-in. Before I buy, I want to know if it's possible to adjust the light brightness in the app for the camera. If it's too bright can the brightness be turned down, can it be turned up if it's not bright enough. I googled and all I could find was info about the battery version which says the brightness cannot be adjusted on that one specifically, but I can't find anywhere that says whether or not brightness can be adjusted in the app on the Ring Spotlight Cam Plus, PLUG IN version
