Magic Keyboard for the 11 inch iPad Air 6th Gen (M2)

Hi, so I've been browsing magic keyboards on Facebook marketplace for a while and I came across a couple deals for the 11 inch version of the iPad Air. They all list that they support the iPad Air 4th gen or iPad Pro 11 Inch 1st & 2nd gen. I am a little confused since I can't find anything on the Apple website or online and have seen some mixed responses. Anyone know anything about this? Thank you!
