iTunesConnect showing "This build is invalid" for app with app clip

I have uploaded my app build with app clip embedded in it to iTunesConnect today using Xcode 12 Beta 6 successfully. After build is processed on iTunesConnect, its showing red exclamation mark & when tapped on it, it says "This build is invalid".

I received below email from AppleStoreConnect mentioning
Code Block
Dear Developer,
We identified one or more issues with a recent
delivery for your app, "MyAppName" 20.36
(3642). Please correct the following issues, then upload again.
ITMS-90865: Thinned app clip size is too large
- The universal variant app clip /Payload/MyAppNameAppClip.app
exceeds the maximum allowable size of 10MB. For details about app
thinning, see: https://help.apple.com/xcode/mac/current/#/devbbdc5ce4f.
Best regards,
The App Store Team


Even though the app clip size is exceeding the 10 MB limit size, I was expecting to see the build details to understand the current app clip size so that I could make the required changes. But I am not able to see the build details at all & hence it will be difficult to know what's going wrong.

Does anyone else faced this issue? How could we check the correct app size of thinned variants to ensure its below 10 MB & ensure build is valid?

How could we check

Perhaps via Xcode's 'app size report'?

Good luck.
Thanks KMT! That helped me a lot!
