For the feature 'Creative Insights' feature description below from Growify website, where is this database sourced from? For example, is the data from live ads currently from Social Media or Google Ads or is this a collection of previous ad promotions from previous date periods.

As a use case, I would like to use this feature as a way to check competitors ads and analyse them, ideally with live ads that are performing well.
