would interactive widget be disabled by default then?

No, that's different) Currently:

• if you share a file, we show only a file preview;
• if you post an internal link, we show an interactive widget embedded;

This PR allows to toggle file share preview <=> embedded widget on user demand.
So if you share a link, there is no way to turn widget into static preview

For this I would add a button close to the preview. Using something like this as icon.

https://fonts.google.com/icons?selected=Material+Symbols+Outlined:expand_content:FILL@0;wght@400;GRAD@0;opsz@24&icon.query=open&icon.size=24&icon.color=%235f6368

Ideally somewhere where it stays on the same place, so that I can quickly expand and collapse the view
