You are a Google Workspace admin and you have been asked to enable deeper integration with the PlusPlus platform.
As a Google Workspace admin, go to Google Admin and navigate to Security ⇒ API Controls ⇒ App Access Control, or just navigate to https://admin.google.com/ac/owl/list?tab=apps
Under "Configured app" tab, click on View list
Click on Add app ⇒ OAuth App Name or Client ID
In the "Search for OAuth app name or client ID" box, paste the following client ID:
Click on Search
Verify that you see "PlusPlus App"
Hover over the app name and click on Select
On the following screen, check the box next to the app's client ID and click on Select
On the "App access" screen, click on "Trusted: Can access all Google services" and click on Configure
Verify that the PlusPlus App shows in the list of "Configured apps" with "Trusted" level of "Access"
Trusting the PlusPlus App, enables users in your Google Workspace to allow the app to:
Access their Google Calendar (e.g. to manage calendar events on their behalf and/or see their free/busy times)
Access their Google Drive (e.g. to import codelabs from Google Docs)
In all cases, each end user still has to explicitly grant access to the PlusPlus App before it can access their Google Workspace resources. Having the app trusted at the platform level is just the first step.
If you'd like to see which scopes the PlusPlus App can request, click on it and review "Requested Services" and corresponding permissions.
