PLugin setup

Hi

We have the plugin set up and the SHOP is working with Facebook.

Just wanted to ask as it created a new business.facebook account for the Catalogue etc I cannot seem to get into the Ad Accounts.
Do I have to create a New One in here to do advertising paid adverts ?

https://business.facebook.com/settings/ad-accounts

We want to do paid adverts for BOTH Facebook & Instagram
Do I have to do it in the new Meta business.facebook account here that was created with your plugin ?

Thanks
Kristin
