Default OBD 2 Scanner for '20-'22 C8's?

Does anyone know of a OBD 2 Scanner that will initiate the transmission fluid flush process on C8's. I know of several that work with '23 an newer C8's but I can't seem to find a consensus opinion on earlier year C8's. (I have a '21) If you've been there/done that, please let me know what manufacturer and model scanner you used. There's also a "Leak Test" that would be handy to have available. I've heard/read about Foxwell and Elite for the later years but can't get any info on the '20-'22 cars. I also sent inquiries to the manufacturers, but they are very slow (3 days out, so far) in responding. My 22.5K flush is coming soon and I'd like to do it myself.

Anyone?

I use my Foxwell NT710 to do all of the flushes and leak tests. Flawless!
