The Salesforce Files tab will show Google Drive as a Connected Source. A custom tab called Google Drive can be created. This tab can have list views like any other tab.
Setting up Files Connect for Google Drive requires administrative access to both Salesforce and the Google Cloud Platform console (the same admin login as G Suite).
It’s best that the same username is used for logging into both. This may mean temporarily making a G Suite admin a Salesforce System Administrator or visa versa.
While the following may seem like a lot of steps, the ability to set up secure server-to-server integration in about 30 minutes represents a tiny sliver of time compared to setting up other types of system integrations.
If your organization is not yet using G Suite, you can try this setup yourself with a free trial of G Suite.
Note: cloud vendors frequently make changes to their user interfaces, so what you see in Salesforce and Google Cloud Platform console may not exactly match all the screen shots below.
