Edge Chromium IE11 compatibility

I’m trying to automate a legacy website through Edge Chromium IE11 compatibility mode.
The site is on the list at edge://compat/enterprise page, meaning the compatibility mode is enabled and I can see the IE11 globe icon next to the URL if Edge is manually opened, and the site is functioning properly.

The problems start when I run Edge via MSEdgeDriver.exe because it ignores compatibility mode.

Is there any desired capability to solve this?

I have the same problem ! Anyone could help us ?
