Plasma Desktop integration with Microsoft Edge is available but ....

You probably know that Microsoft has released the Linux version of the new web browser - Edge based on Chromium.

You can use Edge browser integration with Plasma Desktop by installing " Plasma Integration " in the Chrome web store. In fact, until Plasma 5.21 is released, it will only see it as another Chromium, which means that KRunner, media controls, etc. may not map the browser window correctly or display only a generic icon.
