Which Twitch Ads Manager feature allows for the creation of a custom audience based on viewer interactions with past streams?

Twitch Ads Manager does not directly offer a built-in feature to create custom audiences specifically based on viewer interactions with *paststreams. Twitch's advertising capabilities primarily focus on targeting based on broader categories, interests, and channel affiliations rather than detailed behavioral data from historical stream engagement. Therefore, there is no single, straightforward feature within the Twitch Ads Manager that allows for creating custom audiences using viewer-level interaction data from previous streams. Advertisers typically have to rely on other data sources or partnerships with Twitch to achieve more granular audience targeting based on past stream engagement, or use more general targeting options available within the Ads Manager.
