'Is AppAttest well implemented in my Xcode project?

I had implemented AppCheck for my iOS app project with the vendors DeviceCheck and AppAttest. Here is a screen from my firebase console showing that they're well applied :

But, by checking the AppAttest documentation, I see that line :

"You'll need Xcode 12.5+ to use App Attest."

But I currently have Xcode 12.4 and I can't upgrade this version. So my question is, is AppAttest well implemented to my project ?
