Getting alexa to recognize a new device on matter hub

i’ve got the riddix home assistant matter-hub addon connected to alexa. that worked great on first setup. i added a new entity to the hub, and the hub recognizes it. however i can’t get alexa to re-enumerate the devices and add the new entity. i could potentially decommision it and start over, but i’m guessing that means all my alexa side routines need to get recreated, so i’m concerned about doing tha.

anyone know how to get alexa to discover the new devices through matter hub?

i’ve already tried to tell alexa to discover devices.
