Here we have an extension for presenting Google Slides—replete with customizations—without the requirement of publishing the document to the public web. Access to the Slides presentation is provided via a generated URL, or simply launch it from the extension. Choices for a presentation's slide advance speed and looping behavior are offered from within the extension's popup, as is the option to start a Slides presentation automatically. The extension is available only when a Slides document has been opened for editing. The extension does not collect information of any kind and requires no special permissions.
