M1 MacBook Air Mirror with extended monitor (using pluggable )

To ask my question properly, allow me to explain my set up so it makes sense. I currently have an M1 Macbook Air. I am using " Pluggable" to Extend my screen to 2 external monitors(which is working fine), and I use my M1 MacBook Air's screen as the 3rd monitor. The Pluggable device I bought only allows 2 extended monitors and I have everything hooked up to a j5 Dock.

So my question: Is there a way to MIRROR my M1 MacBook Air's screen to a 3rd external monitor, while still using the Pluggable setup to extend to the 2 external monitors?

I do know Pluggable has a device that allows you to extend more than 2 monitors, but I just wanted to mirror the 3rd external monitor, not extend it.

I have also already tried using an HDMI to USB, and an adapter from USB to USB C to my other USB-C port on my computer but it did not work.

I hope this makes sense

thanks in advance!
