unknown command line argument

[mitttel]

the fragmentary code

iced-webview/src/browser.rs

Line 124 in 620cfa1

command_line.append_switch(Some(&"disable-javascript-open-windows".into()));

There are arguments
disable-javascript-open-windows
disable-chrome-login-prompt
disable-session-crashed-bubble
disable-restore-session-state
I tried to find these arguments on resources with command line tools.
