Storyboards in c# markup

[SonZon2896]

On which page?

https://platform.uno/docs/articles/external/uno.extensions/doc/Learn/Markup/Storyboards.html

What's wrong?

It’s not clear how to use animations (storyboards) in Uno Platform in c# markup.

Any feedback?

This page shows how to declare a Storyboard and how to connect it, but where exactly to declare it is not shown. From the fact that this page is a subsection of the Visual State Manager, we can conclude that the Storyboard needs to be declared there, but the question arises, how to activate the Storyboard, how to set parameters for its activation, etc.
I would like to see an example of what the code would look like that enlarges an object when the button is clicked, and changes its color when hovered.
