integrating zoom meeting sdk

Currently I am working on integrating zoom meeting sdk in react app. So that my react app can start the meeting id set via zoom app.

I had used sdk key and secret from another new email subscribing Video SDK | Pay As You Go

Integration looks successful and the participant shown in waiting state until host start the meeting via app.

But on starting the meeting i am getting following error.

Error:Joining Meeting Timeout or Browser restriction To join a meeting hosted by an external Zoom account, your SDK app has to be published on Zoom Marketplace. You can refer to Section 6.1 of Zoom's API License Terms of Use
