About 64 bits requirement

Hi !

I have a question about the 64 bit requirement by google.

Using the google process for unity here : https://developer.android.com/distribute/best-practices/develop/64-bit and According the documentation: "for each native 32-bit architecture you support you must include the corresponding 64-bit architecture ....... For the ARM architecture, the 32-bit libraries are located in armeabi-v7a. The 64-bit equivalent is arm64-v8a. For the x86 architecture, look for x86 for 32-bit and x86_64 for 64-bit."

But I see my app bundle contain the armeabi-v7a and arm64-v8a, it's fine, I also have x86 but the x86_64 is missing and I don't see any option in unity to add this library, is that normal ? Is it enough for the google requirement to only have the 64 bit architecture for ARM and not for X86 ?

Thank you !
