Allow apps to be registered for tenant
I would like to be able to register custom-built apps in the tenant for use by our organisation. Currently, I can either allow side-loading of apps (not ideal) or publish an app in AppSource and enable it as a third party app. I would prefer not to publish organization-specific applications in AppSource as (1) they don't provide value to anyone outside of the organization and (2) they may contain company confidential information. If Teams would aggregate apps from the company app registry and AppSource, we would be able to restrict third party apps without losing the ability to deploy internally developed apps.
