How open IE11 in private mode?

Hello,

This link https://docs.katalon.com/katalon-studio/docs/start-browsers-in-private-mode.html refers to the desires capabilities for open Chrome and Firefox in private mode.
So not for IE. Why ?
I searched the web selenium capabilities, and found this: “ForceCreateProcessApi=true”,
BrowserCommandLineArguments = “-private” but it does not work.
Can anyone help me please ?
tks
