Hey I want to build a WhatsApp Bot with Botpress for my client, but I don't know how to set up the settings in the Meta center. Right now it is just in the "test mode" like in the tutorial from Botpress. But my client want to have no message limits and the messages should come from the phone number of my client.

test mode indicates that the application you've set up is not verified business app. Probably you'll need to send it to verification to Meta, which means providing business information
