Newly published Zoom OAuth App is not working with outside emails

We have Application “Eltropy-Appointment-Management” published to Marketplace.
But we are not been able to connect to this OAuth application from our Application with personnel gmail accounts.

I am getting below error!!

Application not found
It may have been deleted or you don’t have permission to view it right now.

Please help.

Hello @nagaraju usually that would be the error if you try to use the dev credentials externally only production credentials can be used externally.
