FCP for Private instance

Hi,

We are using private instance of WPT to measure the performance of our site. Lately we came across a new feature added in the public WPT named FCP which wasn’t included in private instance:huh:. Can anyone let me know how to include FCP metric in to the private instance of WPT.

Thanks,
Prasanth

I would also be curious about this. Not necessarily about how to add that metric but why it displays differently anyway. It makes me feel like something is missing in our setup.
