Not able to setup, modify or start RTMP in Zoom API account

Hi All

We are trying to use the Zoom meeting API to start to add custom RTMP URL and start the broadcast(after the meeting has been created of course).

The account we have is an API Plan and does not seem to have the option to use the custome RTMP functionality as when I search in the account settings for any reference to RTMP, nothing appears(it is not the same in our Enterprise named licenses account where the option appears and we ar eable to interact with it)

Anybody has come across this and knows how to help?

Thank you in advance
