Find My Apple wrong name

Hello everyone

Recently I bought a MacBook Pro 2020 second hand but I have a problem that I couldn't figure out.

Every time I leave my home and leave my laptop behind, Find My Apple send me a notification, saying that 'Alex's MacBook Pro' was forgotten. Lastly seen on Home location.

The problem is the previous owner was named 'Alex' and I want to change that but I couldn't figure out how.

I removed every 'Alex' I could find in my MacBook but still when I'm go out it's send me the same notification

It's my first time with Apple ecosystem. I am normally Android and Windows user.

Thanks in advance
