How do I cancel my MUBI on Amazon Prime?

Hello there, I'm wondering if you could help me out with a question about MUBI and Amazon Prime. I've subscribed to MUBI through Amazon Prime and now I'm looking to cancel my subscription. Could you walk me through the steps on how to do that? I've been trying to find the option on the Amazon website, but I'm not sure where exactly it is. I'd really appreciate it if you could provide me with some guidance on this matter. Thank you in advance!
