Does anyone techie know how to set a specific song as a ringtone?

[Gracelet]

Just that really! I'd like to set a song as a ringtone on my iPhone (16, Pro Max).

Grateful for any help!

TIA

You have to buy a ring tone version of it from the iTunes store. Go on the app click the 3 dots on the right hand side, select tones and buy the one you want

Or this. Which is extremely long winded
