When you add a G Suite Admin card to a Flow for the first time, you'll be prompted to create a connection. Connecting your account will enable you to save your account information and reuse that connection the next time you build a Flow with the connector.
Note: You can create multiple connections and manage them from your Settings page as well as share them with your team.
To create a new connection from an Action card:
Click New Connection.
Enter a Connection Nickname. As a best practice, make this nickname unique so that you can connect multiple G Suite Admin accounts.
Enter your Domain.
