The "on system lock" timeout option doesn't work with the Chrome extension in Linux

This is more of a bug report than a feature request.

The Bitwarden Chrome extension doesn’t seem to detect the system lock state on Linux. I have tried it with both ‘xlockmore’ (cmd: xlock) and KDE’s ‘kscreenlocker’ (cmd: kscreenlocker_greet).

Is there any way to get this working without my needing to install and run the desktop application? I prefer to keep things minimal. Thanks in advance.
