Schatterjee,
You didn’t understand what is asked here. We know how to use the fullscreen features and the point is that we would like to automate it via an URL action or something.
Here is a small example with a google link from a slides :
[https://docs.google.com/presentation/d/link/
edit
?slide=id](https://docs.google.com/presentation/d/link/edit?slide=id) → with this link I have a presentation in edit mode. But if I change the “edit” and replace it by “presentation”
[https://docs.google.com/presentation/d/link/
present
?slide=id](https://docs.google.com/presentation/d/link/edit?slide=id) → with this link I have a presentation in edit mode with means that when I open the link it’s directly in full screen size.
I’m almost sure that when we use your fullscreen features it generates a specific URL or whatever but it is a basic, worldwide common and essential feature in any data visualisation tool embeded online.
