Form submit with input file - Next js + craft cms headless

[kaduppg]

Hey guys, I was wondering what is the best solution when it comes to submit a form with a file input? Should I use mutation or create a controller? If so ... how can i link the file uploaded with the assets ? If there's any tutorial please let me know.

Cheers.
