How do I set up a WiFi dongle with this? [Libre Potato]

I've seen the question asked many times but never a straight answer: How do I get LibreElec to recognize my WiFi dongle on a Libre Computer Potato?

This here is my dongle. Seems fairly standard - I plug it in with LibreElec running but nothing happens, and the connections window stays empty.

I am new to LibreElec (and Libre Computer), so perhaps I'm just not aware of something - I really hope there's a way to make this wireless dongle to work though, I'd really prefer to use something small and direct rather than setting up a new router and connecting that with an ethernet cable.

Any help would be greatly appreciated!

Thank you
