How does it work?

The plugin itself is at its core just a simple web application built with React, hosted on Github (on our Github page). You can browse it like any other web app, but it won't do you much good.
It's much more useful when embedded as a plugin on Miro. Thanks to their Software Development Kit (SDK), the app can communicate with Miro and ask it to do things like creating and modifying elements on a board.

To get data about codebeamer Items, the app queries the codebeamer REST API via the Internet, using the authenticated user's credentials.
