How do I cancel my Metro bike?

Hello there! I'm wondering if you could help me out with a question about cancelling a Metro bike subscription. I've been using the service for a while now, but I'm thinking of switching to a different mode of transportation. I've looked through the Metro bike website and the app, but I can't seem to find a clear way to cancel my subscription. Could you possibly walk me through the process? I'd really appreciate your help with this. Thank you in advance!
