Hi @frob ,
I will recommend you to use Fluent UI to achieve your requirement. TeachingBubbles are a special kind of Callout used to prominently display important hints to a specific part of a page. They should be used to educate the user about an element that may be easy to miss, such as a new feature or option in the UI. Because they increase engagement with a part of the UI, they are often paired with Coachmarks. You can follow the steps in the article.
