Which description below best describes the action you would undertake in this dialog box?

The dialog box in question is specifically designed for connecting social media accounts to Hootsuite. Adding an Instagram account is a common initial step for managing your Instagram presence through the platform. Creating a stream involves displaying content from a connected account, not the initial connection itself. Sharing account permissions with your team is a separate administrative function, typically found in team or organization settings. Scheduling a post and composing a message are actions performed after an account has been successfully added to Hootsuite. Therefore, the most accurate description of the action in this context is adding an Instagram account.
