"""Google Cloud Live Stream sample for creating a channel event. An event is a
    sub-resource of a channel, which can be scheduled by the user to execute
    operations on a channel resource without having to stop the channel.
Example usage:
    python create_channel_event.py --project_id <project-id> --location <location> \
        --channel_id <channel-id> --event_id <event-id>
