【UE4】【GLES version not specified】【App laboratory review BUG submission】 ”android:glEsVersion“

I use Unreal 4 and it’s set up【AndroidManifest.xml】-》【android:glEsVersion="0x00030001"】，But the audit system still tells me the error！

The shader I use is valkan, not OpenGL, Unreal Engine, and it is not easy to develop mobile devices. We have spent 2 years preparing this project. Please help us, let our little chickens become virtual Players of the world, say "Hello, world!"
