Click on Enable checkbox. Insert the client ID into Google Client ID field and click 'Save' button. Please make sure to put a correct client ID since wrong value can break functionality of Work Time Calendar for all users.
You can leave the calendar table empty so users configure their own calendars. Other option is to set calendars that are common for your company or all Jira users. Here you can add up to 4 calendars. Good candidates for common calendars are state holidays and your company calendars. You can find a list of all public calendars by opening your Google calendar, clicking the drop-down menu near "Other calendars" and selecting "Browse Interesting Calendars".
