Restoring 3-month Apple Music trial for AirPods 4 purchase

Hi, I recently bought a pair of AirPods 4, and I got the 3-month free Apple Music trial that came with it.

But I accidentally canceled the trial, and now I can’t redeem it again.

Could you please help me restore the 3-month Apple Music offer?

I still have my purchase receipt if needed.

Thank you very much!
