Hi, how to e2e-test a communication using a WABA account? I'm using Twilio as solution partner to send OTP using their Verify API. The API is linked with our own WhatsApp Phone Number (WABA), but I currently do not see a way how to receive that messages and to get a webhook called. Twilio offeres to register multiple numbers but these numbers have to refer a WABA. According to Meta documentation, a WABA could not send a message to another WABA, so how to test this? All I want is to get a webhook called on an incoming message that contains the message body.
