How can I reactivate my canceled Apple Music free trial?

I recently purchased a Mac and activated the 3-month free Apple Music subscription, but I accidentally canceled it after just a few minutes. Unfortunately, I can no longer reactivate the offer, even though I barely used the service.

Could you please help me restore the free trial period or advise me on a possible solution?

Thank you in advance for your support!
