Better monitoring support for single page applications (SPA)

We've setup a test for a SPA but do not get web vital metrics (FCP, LCP, ...) for the subnavigation. To retrieve those metrics chromium offers a browser flag "--enable-experimental-web-platform-features" (see https://estelafranco.com/blog/spa-cwv/)

But enabling the flag in the script like

...
const browser = await chromium.launch({ headless: false, args: ['--enable-experimental-web-platform-features'] });
...

end up in a error:

...
Warning: chromium launch argument "--enable-experimental-web-platform-features" is not whitelisted by Checkly and will be ignored. If you need to use this argument, please contact support.
...


So it would be great if you could add the flag to the not blocked falgs.

Kind regards
