Apple-Should list All Devices an Apple User OWNED under Apple Sign-In !!

Why doesn’t Apple Support have Ability to -Access Devices Presently and past OWNED per Customer ?

APPLE should provide this Service !!

Apple: ID and Password, Customers should have this information available.

Especially if lost purchase receipt .

Also if a Cell Phone-Service Provider( ie Verizon) switched Apple-IPhone 12.

Got another IPhone 12 and is smaller.

HELP-Fix this POOR Support on Apple-Sign In.

This service would help me verify Verizon didn’t return my Original-IPhone 12.

Please HELP !
