Which javascript action to unzoom to fit at 100% the document

Using JavaScript with Hype
1

Hi,
I have a document on which my customer want to be able to zoom in the entire scene (pinch gesture in a browser).
But when they find a button on the scene and clic it, I want to zoom out to come back to 100% to see the entire document (or scene).

What is the javascript code I can trigger with the button to zoom the whole scene back to 100% ?

Kind regards,

Vincent

found this

https://lab.hakim.se/zoom-js/

and that

Maybe something helps.

Not an easy task if you don’t control the zoom to begin with.
