ROCK 4 SE Wireless Chip Missing

I have been attempting to use this guide here:
to set up my ROCK 4 SE as an access point. However, it is lacking in detail and doesn’t seem to work. I also notice when I run the command ‘lsusb’, the wireless chip (Realtek xxxxxx) is not listed there.
I am using the Debian Buster download from the Radxa website.

Could someone write a more detailed and up-to-date guide, or does anyone have a fix for this issue?
