How to transfer music from huawei p10 to iphone 11 pro?

I've had my iphone 11 pro for 6 months and was able to transfer everything except the music that I download from snaptube that is on google music. My stepdad tried it but he had to pay for it, which still didn't work, so that you can plug both into your laptop and transfer it

The music may be in a file format that doesn't work on an iPhone. Then you can't upload it.

There's also Google Play Music for iOS.
