How to remove First Alert Smoke/CO detector that I no longer own?

I recently moved, and I left behind two First Alert Smoke/CO detectors at the old house, but I brought my SmartThings hub with me.

I’m now setting the hub up in my new location, and I cannot remove the old smoke detectors because I do not have access to them to perform the exclusion procedure.

How can I get rid of these things? I don’t like having them show up in the app when they are now worthless to me.
