Something I did once as I had screens for a 10x10 free standing canopy laying around. I clipped those screens on my awning. It did OK considering it wasn’t made for it but my awning is 12’ wide. I also had no clue how To attach It to my popup or what to do with the excess material. It might not work too well if your awning is wider as the door would be harder to line up without leaving wide open gaps. my screens was one very long panel that would typically wrap around the 10x10.
