How Do I Change The SDK?

I have made a very basic app (just my website inside it) and was going through the process of submitting it to my first app store and the amazon app store wants me to change the sdk to 22 or lower because that’s what it’s devices support. I tried to open it in android studio but got really confused. Does anyone know an easier way or maybe willing to change it for me?

I haven’t uploaded any apps to the Amazon store but requiring version in 2021 is a bit of a surprise! Can you post a screenshot of the message you receive about this requirement? Thanks
