Magic Keyboard Touch Id not working on Macbook Pro

Hello,

I have a Macbook Pro 2020 with Touch Id on native keyboard.

As I work a lot with external screen and external keyboard I decided to buy Magic Keyboard instead of random keyboards with windows key.

So, I went ahead to buy the Magic Keyboard with Touch Id.

I can't figure out why I can't use touch ID on external keyboard, just allows me to use the native keyboard magic ID.

I already tried to remove all finger memories and add just on external, tried with cable instead of bluetooth, nothing seems to work...
