When your teacher shares an URL, you will not be automatically redirected to this URL, so you can finish what you are doing.
When ready, just click on Home to open the link. You can then interact with the web page and navigate from this starting point.
When you click again on Home, you will be redirected to the latest URL shared by the teacher.
Using Back and Forward buttons, you can navigate through all the URLs received or visited during the session.
