Supported Engin Versions ?

I am very new to the marketplace, so I am sorry if my question sounds stupid. I looked it up in the forums and I couldn’t find the answer to my question.
My name is Olivier Girardot, I am s Sound Designer and a Composer. I am submitting my first sound effect packs to the marketplace but I am not sure what “Supported Engine Versions” I can mention. I created my sound packs with Unreal Engine 4.21.0. Will my sound pack be compatible with previous engine versions ?
Thank you in advance for your replies.
Best regards,
Olivier Girardot
