I am trying to automatically install a Microsoft Edge Extension in an enterprise managed environment: Google Chrome allow this behavior (check this post for further information), but it seems impossible to do the same for Edge (the Edge extension policy states that "The installation must be initiated and completed by the user, using only the user experience provided by Microsoft Edge and the Microsoft Store").

The new Microsoft Edge based on Chromium supports GPOs (cfr. https://learn.microsoft.com/en-us/deployedge/microsoft-edge-policies#extensioninstallforcelist)
