F7 key on 67% keyboard

SOLVED: i used the simulate input action on opendeck and set it to f7. yes i have a streamdeck

so i use a program where you need to press f7 and you cant change it, but i only have a 67% keyboard and the layout i have selected in my keyboard setting doesnt seem to have fn on any of my keys so pls help

EDIT: just so you guys know i have a streamdeck that i can use but idrk how to configure a button to be f7
