Existing accounts hierarchy and New Authorisation Requirements (OBF and ZAK tokens)

In our application, we use the Zoom Meeting SDK. Users of our mobile application are able to join Zoom meetings that are pre-created on our website.

The users are not aware of Zoom and do not use Zoom accounts to sign in.

We have a main Zoom account for our company, as well as sub-accounts. Our application was created under one of the sub-accounts, while the Zoom meetings are created using the main Zoom account.

Could you please advise whether any changes are required to our Zoom account hierarchy, or whether we need to implement On Behalf Of (OBF) tokens or ZAK tokens?

Would it be sufficient to move the application to the main Zoom account?
