How can I implement the fancy tooltips that mkdocs material uses for their own docs?

I stumbled over the tooltips feature to create a glossary, and this is exactly what I want.

But I was wondering how I can implement a tooltip like the following (that mkdocs material uses themselves):

I was checking the source code of the page to see how it is done, and it is just referencing the original section there.

When I implement it like this, all I get is a regular link to the corresponding markdown section (which is somehow expected because it is the regular syntax for markdown links), but no tooltip.

So I was wondering what am I missing and how mkdocs material is doing it themselves. Am I missing some configuration?

Those nice little fancy tooltips are called Instant previews and are available to our sponsors as part of Insiders ☺️

Cool stuff, @squidfunk 🙌🏼

Also, I wanted to say, I use mkdocs material for a university course I am teaching and it is the perfect tool for that 😍

Thank you!
