This tour is focused on the convenience of the user.
Therefore, in the event of a page refresh, the tour will automatically recover and continue from the place where it stopped.
This ability can be used when:
1. Page updated manually.
2. Page refreshes after form submission.
3. During the tour, a transition to another page occurs by clicking on the link.
This example will not work on your local disk, since other urls are specified in the "loc" parameter
