Last step: connect your WhatsApp number.
Everything you set up here - documents, details, tone - is saved and ready; your assistant just can't answer until your number is connected.
Connect your number whenever you're ready.
One setting to switch off first: in the WhatsApp Business app, turn OFF Greeting message and Away message (Business tools). Your assistant replies 24/7, so they're redundant - and worse, they mute it: an auto-reply looks like you stepping into the chat, so your assistant politely goes quiet. Replying yourself, or sending a quick reply by hand, is always fine - that pause is by design.
