I’ve seen in other entries that we should have our admin go to Sign In | Zoom to add the developer role to the user. However, when our admin user tries to access that page we get an access restricted 200 response. The two images below show our admin user and the response from that page when trying to access it with that admin user.
Thanks for reaching out to us!
It looks like the Admin role under the account does not have role management permissions
My suggestion would be to ask the owner of the account to create a new role and assign it to the user who created the app (Developer role)
