iTunes 12.6.5.3 on Apple Silicon

I was just wondering, can you make the same instructions but for the one Bundled with macOS Mojave?

then run the additional commands

And also, the strings are just 13.9.9 as this or should it be 13.9.5.5? Or just 13.9.5?

The important thing is to replace 12 with 13. The rest of the numbers shouldn't matter.

I am also getting that error when iTunes opens, and I think it's the connection with iTunes Store, so it won't let me access the iTunes Store in anyway.
