Hi @Mario Del Mastro ,
Unfortunately, it is not possible to hide that "Open browser window" button. But I do have some workarounds for you to avoid navigating to other pages (if it is your main purpose).
- Block all sites but allow the target site. You can configure the following 2 group policies:
Block access to a list of URLs > *
Define a list of allowed URLs > https://www.microsoft.com (or other URLs) - Use Kiosk mode. The following command line flag will force Edge into fullscreen, not allowing users to navigate to other sites:
--kiosk www.contoso.com --edge-kiosk-type=fullscreen
