Lazy load Performance module

[Parakoos]

I have successfully cut down on the initial load time for my Nuxt/Firebase statically generated app by using your amazing lazy load functionality. (btw, I tried to do this on my own before and failed! thanks!)

Now I want to add the Performance module, and I know I have to call something like:

if (process.client) {
    await this.$fire.performanceReady()
}

Is that enough to start logging performance data like network requests etc? Or do I need to do something more? Perhaps set this.$fire.performance.instrumentationEnabled to true

And, where in a typical Nuxt app would you call this? I don't want the loading of the script to delay my user's interaction with my site, but I'm worrying that initializing it lazily will mean it never gets the various traces right, such as 'first contentful paint', considering that it might start the clock too late.

I looked around the documentation but didn't see any references to this.
