Edge Canary installs itself in 2 places

C:\Users\username\AppData\Local\Microsoft\EdgeCore\91.0.852.0
C:\Users\username\AppData\Local\Microsoft\Edge SxS\Application\91.0.852.0

user profile directory is only in "Edge SxS" folder though.

I'm not sure what "EdgeCore" folder and a copy of the browser in there is for.
