How to change raspberry pi pico keyboard language

So i have 2 raspberry pi pico. My problem is that when i try to make it into a badusb it uses american keyboard layout. So when i want it to write example a "." it presses the . icon on a american keyboard wich isnt the same place for my swedish keyboard. I dont know how to fix this. I would assume the peope here outside of USA have exprianced this issue before since the language is American when it comes from the factory. Thank you for help!
