Accessing the Zoom JavaScript SDK

Description
My team and I are trying to develop an app for the Zoom Marketplace following this documentation. So far, we have been able to whitelist our domain and also able to create and install our app for local tests.

However, the documentation mentioned the availability of the JavaScript SDK which should give us access to zoom APIs for us to create the magic we want to, but we do not know where to access the JavaScript SDK. From this sdk documentation, there was no mention of JavaScript SDK and we do believe the JavaScript SDK used within the Zoom App context is different from the WebSDK in the documentation.

NOTE: We have not received an invite to join the #Zoom Apps Announcements channel as mentioned in the first documentation link I shared
