Feature Request: Support for Chrome Launch Flags (e.g. screen sharing automation)

I’m currently trying to automate a test that involves screen sharing (e.g. clicking a “Share screen” button that triggers the browser’s native screen picker dialog). As you know, due to browser security restrictions, this dialog cannot be controlled via JavaScript or DOM automation.

In tools like Puppeteer or Playwright, this limitation is usually bypassed by launching Chrome with specific flags, such as:

--use-fake-ui-for-media-stream

--enable-usermedia-screen-capturing

--auto-select-desktop-capture-source="Entire screen"

I would like to request the ability to configure such Chrome launch flags in BugBug test settings or project setup. This feature would be incredibly useful for testing scenarios that involve media devices, screen sharing, or permissions.

Would it be possible to consider adding support for this in a future release?
