Invalid Token error message shown on Salesforce record page

in my salesforce org, have set up Zoom meeting integration, and obtained the Zoom API key and Secret key by creating OAuth app. and now it’s the Token issue. here’s the message:

Invalid access token, please contact your admin

what should I do to pass this?

Hi @suping.cao

Thanks for reaching out to the Zoom Developer Forum and welcome to our community!
Are you still experiencing this issue? or have you been able to solve it?

Let me know if there is anything else I can do to support you here!
Best, ,

I am glad you reaching out Elisa, I still have that issue. but one thing I wanted to know to first - do I need Zoom admin permission to obtain the token?
