MacAir M2, Kensington SD5500T, dual HP x24ih Monitors not working

I recently decided to "upgrade" to a Mac from windows. Possibly a huge mistake, as I didn't realize how much I took for granted on Windows that was just simple to do.

That said, I'm giving this Mac a try but have been hitting a wall for days with trying to get it to work with dual monitors, which I really like to have after having gotten used to them at work.

I bought a Kensington SD5500T docking station after reading around and seeing that lots of people had luck with getting it to run dual monitors. I've tried every combination possible of DisplayPort, HDMI, adapters etc to connect my monitors to the dock, but no matter what I do, I can only get one monitor to work. The dock is being detected by the Mac. I;m 99% certain that the one monitor I can get to work is only because that monitor is being natively detected by MacOS, NOT because of the DisplayLink driver.

I've installed DisplayLink driver, and while I have all the permissions enabled for it, it just doesn't seem to be detecting either monitor. I'm sure some of the problem may be my infamiliarity with MacOS, however even a poorly trained monkey can usually repeat what it sees, and I've been completely unable to repeat any of the myriad of videos I've found online demonstrating my Mac running dual external monitors with this setup.

Any help/advice?

For reference:
