I have been going through docs for days and I am still unable to find whether WABA numbers can be used for Conversion API for business messaging. we have a WhatsApp-centric sales journey and our leads come from CTWA campaigns thus we need to use Conversion API business messaging to attribute the leads and track the conversion funnel.

is App Review on the app necessary to get the extended access of whatsapp_business_messaging permission?

how do I link my WABA numbers to the webhook? surely they have to be linked through the app, right? how do I link the WABA numbers I already have in WhatsApp Manager to the app? if I use the "Manage phone numbers" button on the WhatsApp -> Configuration on the developers dashboard, it will create a new WhatsApp account profile in WhatsApp Manager.

it's crazy how a feature announced at an event as important as WhatsApp Business Summit is so difficult to find and implement
