Site Info and Contact Form Settings - new Google Sites

Instructions

Use the Settings (looks like a cog/gear) near the Publish button.
Choose the Viewer tools option.
In the Info icon section use the slider to enable/disable the options for:
- Show page last updated time
- Show contact form (only available for Google Workspace)
Close the Settings dialogue box.
Use the Publish button to hide the anchor links (header links) on the live site.

The info shows the date or time of the latest update to the page you view, not the site in general.
This now removes the "created using the new Google sites" strapline from the footer.
The Report Abuse link is now hidden in this site info.
If you are signed in as a Google Workspace admin you get offered the Admin link to get the Site Details (Site owner and request access).
If you choose to Show contact form this is only available to Google Workspace based new Google Sites, at the sites.google.com published URL, when the viewer is signed in a an account.
