BLE / FindMyMod feature

I have a small key chain called tile.
It's connected to my phone using BLE and an app on the phone checks every now and then if the key chain is still in sight. If not, the phone records the current position.
If I can't find my phone, I double press the button on the key chain and my phone rings.
If I can't find my keys, I push a button on the phone app and the key chain rings.

I would love to have the same feature integrated in my mod, because I often have to search for it.
