Hi, I would like to connect rudderstack and Facebook offline conversions. While connecting with Facebook it's showing to enter System User Access Token. In order to get whole data, we should have to enable permission while creating an access token. As per the facebook business manager setup, we should have enabled the App before setting up the access token. If I am creating an access token before adding the app to the business manager, the token doesn't have permission to access the whole data. In this case what we can do?
