Once you have it, you should see stories in VSCode similar to this:
2-Step Process to Create your own story
Step One
You can click the Stories Icon button or open up the panel to access the stories.
Once you have that open up, click on anyone's profile picture, and you'll be shown a snippet of their code of what they're currently working on, thus Stories!
Step Two
To upload your own story, click the Create Story button on the bottom right.
And voila, you published your very own VSCode Story!
