Linking Known devices with people and groups

Configuration
1

I guess im missing something obvious.
I have a known devices config, I have a person(me).
The question is, how do I link my “known device” my phone, to person me.

Probably very easy, but after days of trying, I can see the wood for the trees.
It would also be nice if I could do something with my many other known devices, I have no idea what? grouping them maybe? what do you suggest?
Can you help?

configuration > integrations > persons
then you can add device trackers to your person.

3

is your known devices (phone) listed as device trackers?
I believe only device trackers can be linked to person component

configuration > integrations > ## I don’t have persons. Only Google cast: Met No.: and MQTT:
I have configuration > Persons ,but I cant seem to do anything in this, just NAME, LINKED USER, and ADD A DEVICE TO BE TRACKED, of which my phone is not shown.

Im using ee bright box integration.
