@RL_Dane am able to detect and view the device in mind via map in the app. I'm not sure how useful it will be when locating when lost tho. Doesn't seem to be an option to ring devices or notify if a disconnect occurs. I've got one of those BLE/GPS tracker card for my wallet. So far the only way I'm able to use it on my Pixel 8 running Graphene is via sandboxed Google Services being installed. Bummer to resort to that for one thing only when I have no other use for them.
