How to get a refund for an accidental app subscription on Apple Pay?

Hi

Two days ago i canceled a subscription made accidentally by my friend and i also made a refund request and it was accepted.

Now,i received a credit note from apple about my purchase and i do not understand what to do with this.I would like to know how i could get my money. back.The purchase was made through Apple Pay from Revolut.

I will leave you a screenshot of my credit note.

If someone could please reply to me!
