Required. The custom class to update.

The custom class's `name` field is used to identify the custom class to be
updated. Format:

`projects/{project}/locations/{location}/customClasses/{custom_class}`

Speech-to-Text supports three locations: `global`, `us` (US North America),
and `eu` (Europe). If you are calling the `speech.googleapis.com`
endpoint, use the `global` location. To specify a region, use a
[regional endpoint](https://cloud.google.com/speech-to-text/docs/endpoints)
with matching `us` or `eu` location value.
