My kingdom for a built in tool example like CalendarToolSet for google calendar.

[jeffbryner]

Is your feature request related to a problem? Please describe.

There are no working examples for the built in oauth google tools like calendar, drive, etc.

Describe the solution you'd like

Even gemini would love a simple example of how to use the built in tools like CalendarToolSet

Describe alternatives you've considered

I tried asking gemin, but it invented apis.

Additional context

Some examples of built in tools exist, just not for built in oauth/google workspace tools.

I've tried adkweb with some simple examples, but no joy:

from google.adk.agents import Agent
from google.adk.tools.google_api_tool import CalendarToolset

oauth_client_id="<secret from somewhere>"
oauth_client_secret="<secret from somewhere>"

calendar_tool_set = CalendarToolset(
    client_id=oauth_client_id, client_secret=oauth_client_secret
)
root_agent = Agent(
    model="gemini-2.5-pro",
    name="calendar_agent",
    instruction="You are an expert scheduler with access to Google Calendar.",
    tools=[calendar_tool_set],
)

It does go as far as requesting authorization, but does not offer a URI or other means to obtain it.
