Instagram Custom Audiences
To create an Engagement Custom Audience of people who've engaged with your Instagram business profile: Go to your Audiences. Click the Create Audience dropdown and choose Custom Audience. Note: If you've never created an audience of any kind before, you'll see Create a Custom Audiences button, not a dropdown. Everything else will be the same.
