What credentials I should use in CRM?

In CRM the Zoom module is using JWT (Zoom API Key) and (Zoom API Secret). Not when I go to OAuth (since JWT is greyed out now), then I only find Client ID and Client secret. So what should I do now with all of it?
And also this URL (the one that starts with Error - Zoom…) What should I do with it? In the module it’s not mentioned.
What was the point to abandon JWT? To make our life harder? Why to fix something that isn’t broken. Well, it’s your business. You do what you want.
Best regards,
