Description

What happened?

I am using the latest 134 release of the WebView and tried to open the CDP traffic setting the environment variable:

WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS="--remote-debugging-port=9224 --remote-allow-origins=* "

or

WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS="--remote-debugging-port=9224 --remote-allow-origins=ip_address "

In both cases, using netstat, the port 9224 is only opened on localhost.

Is this a bug, a wrong configuration or a missing flag?

Thank you
