Good morning. Can someone advise me on how I do the following process please.

I’m using a DSLR and have taken my lights, darks, flats and bias frames of the American Nebula and have them on my desktop. If I run APP I get a great image of the American Nebula showing it in the H-Alpha red colour. Whilst that looks great I’ve seen the same composition which was processed combining just the RGB & HOO channels and would love to know how I do this in APP??
