Removing permission previously given to a automatic recording and note taking app

Hi all, I recently gave permission to an App called otter.ai that records meetings. I changed my mind and want to remove the permission previously given. How do I do this ?

I have tried using the "Manage" button on Zoom market place. But nowhere can I see this app mentioned. As I already deleted my account with otter.ai does this mean it automatically removed itself from my Zoom permissions OR is there sometjing more I need to do to achieve this. 

Thank you for your comments and step by step guidance as needed.

Best, David
