MetricKit: responsibility for processing Payloads?

Having read several posts on MetricKit and I'm very confused!

I understand that:
Code Block
didReceive(_ payloads: [MXMetricPayload])

gets called with payloads containing performance data.

However as a developer do I need todo anything with this data or can I just leave it up-to Apple for processing? How does this data find its way to Apples servers for download to Xcode organiser?

There is obviously a big bit of the story that I am missing!
It's up to you to process MXMetricPayloads (and optionally upload to your own server).
