How can one open a browser: edge or chrome or firefox, to specific pixel dimensions?

Question

I have tried the following shortcut for edge, with no success:

Shortcut Definition:

Target:

"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --profile-directory=Default --window-size=800,900

Start in:

"C:\Program Files (x86)\Microsoft\Edge\Application"

The window opens ignoring the specified window size.
