Apple sing (karaoke) feature, on MacOs

I have an iPhone 11 Pro, and I do have the sing (karaoke) feature on my Apple Music app, but from some reason in my MacBook Pro 2001 M1 chip I do not have that feature.

I understand that right now it is for iPhone and iPad only.

But I do not understand it why?

Why it is limited for just this two platforms obviously the MacBook M1 (for an example) have better ‏hardware than the iPhone 11..
