Since Instagram is owned by Facebook, some of its requirements (especially for connecting with 3rd party APIs) include connecting the Insta business page with a Facebook business manager.

Setting up an Insta business page
Connect an Instagram Business Profile to a Facebook Page or Change the Facebook Page associated with your Instagram Business Profile
