enum

Reason an inbox is not fully active. - `payment_issue`: WhatsApp rejects business-initiated messages until the WhatsApp Business Account has a working payment method. - `phone_number_not_found`: WhatsApp no longer lists the inbox's phone number on its WhatsApp Business Account, for example because it was deleted in WhatsApp Manager. The inbox is `unavailable`. - `reconnect_required`: Meta no longer accepts the inbox's stored access, or it lost access to the account. Connect the channel again. The inbox is `unavailable`.
