Recent product update with regard to Orchestrator. Want to understand if it support this use case?

As client doesn’t have WhatsApp number so requirement is to connect the WA Orchestrator and proceed with the development, testing and UAT. While we were trying to create the Orchestrator bot referring to the video shared, we could not link it to the Subscription id. It is disabled. Can someone advise if we are going wrong anywhere?
