Connections is where you can see and manage all the different connections to 3rd party data sources you have created in Grow.
You can use the search bar to quickly find a specific connection.
You can check 'Show only my Connections' to find all the connections you have access to manage or ones you created.
You can check 'Show only broken Connections' to see only the connections that have become disconnected and need your attention to fix.
From this page you can also create new connections by clicking the 'Add Connection' button.
