• Search or ask on StackOverflow (engineers monitor these tags): doesn't appear

3. Do you have a support contract?
   No

Environment details

• googleapis version: 140.0.1 (latest)

Steps to reproduce

import { google } from 'googleapis';
const service = google.tasks({ version: 'v1', auth });
 const tasksResult = await service.tasks.list({
        tasklist: tasklistId!,
       showCompleted: true,
        showHidden: true,
       showDeleted: true,
       showAssigned: true, 
      });

2. error appears: Object literal may only specify known properties, and showAssigned does not exist in type

I see it appears on the source typescript code of this repo, but not in the build typescript types

Thanks!
