Hi, the Anychat platform seems to be of great use. But, I am facing some problem. While integrating the WhatsApp Business app, it initially asked for four types of information. 1. Access token, 2. App ID, 3. WhatsApp Business Account ID, and 4. Phone No. ID. I am clear about all except App ID. Where can one find this App ID? Also, if we proceed anyway entering some ID, it asks for further integrations like webhook url and verify token- what to do with them? There is no information in the documentation. Kinldy clarify.
