How do I stop recurring purchases on Coinbase?

Could you please enlighten me on how to disable automatic purchases on Coinbase? I've been noticing that certain transactions are being debited from my account repeatedly, and I'm not entirely certain how to halt them. I've explored the platform but haven't found a clear solution. Could you guide me through the steps necessary to stop these recurring purchases? It would be greatly appreciated if you could provide a detailed explanation of the process. I'm aiming to maintain better control of my finances, and stopping these recurring purchases seems to be a crucial step in that direction. Thank you for your assistance in this matter.
