How can I change the recipient of the "Payment Success" email, even manually by modifying the necessary variable, so that payment confirmation emails are always sent to the store manager (my mail) instead?

Good morning,
I would like to know where I can change the recipient of the "Payment Success" email — even manually, by modifying the necessary variable — so that payment confirmation emails are always and only sent to the store manager. Receiving an email that always shows as unpaid is not helpful.
