I have created an app for Enterprise DNA Forum.
Well, sort of, let me explain.
In the Microsoft Edge browser, I created the app by:
Settings (the 3 dots in the top right) > Apps > Install this site as an app
Then pinned the app to the taskbar.
It’s like a browser without all the menus and buttons etc.
I am using version 80.0.361.111 (Official build) (64-bit), unsure if available for earlier versions.
