Incomplete documentation on the Telemetry API

- OS: Windows 10 21H2
- Node.js version: 14.16.0
- npm version: 8.1.2
- `googleapis` version: 105.0.0

#### Steps to reproduce

- There is no documentation for the Telemetry API in official documentation: https://googleapis.dev/nodejs/googleapis/latest/chromemanagement/classes/Chromemanagement.html

- In [repository documentation](https://github.com/googleapis/google-api-nodejs-client/blob/432ce2dccd56b308b5d3ebaaf6233a279d026858/discovery/chromemanagement-v1.json), description of `parent` in `telemetry.devices.list` is :
`Required. Customer id or \"my_customer\" to use the customer associated to the account making the request.`.
But right Customer id to use the customer associated to the account making the request is `\"customer/my_customer\"`

```javascript
const chromemanagement = google.chromemanagement({
version: 'v1',
auth: oAuth2Client
});

const telemetry = await chromemanagement.customers.telemetry.devices.list({
parent: 'my_customer',
readMask: 'name'
}) // Throw error: "The requested URL /v1/my_customer/telemetry/devices was not found on this server."
