Unlock HyperOS Bootloader on Chinese Device

I have seen many posts about unlocking the bootloader on *global* devices, like this one.
I proceeded as in the steps described, but I still can't unlock the bootloader. When I try to add my account in developer options, it still says "apply for authorization"

I don't know what to do, because I have a brand new Xiaomi 14 with chinese HyperOS installed and I like to install Eu Rom from xiaomi.eu.

Any help would be very appreciated...
