How to map UTM parameters?

You can create a custom attribute for any additional fields you need. Check out the docs here.

RevenueCat has these attributes related to campaign data:

• $mediaSource
• $campaign
• $adGroup
• $ad
• $keyword
• $creative

We have these UTM parameters:

• utm_source
• utm_medium
• utm_campaign
• utm_term
• utm_content

I know that we can call this function to setup the RevenueCat campaign data attributes:

  Purchases.setAttributes({
    $mediaSource: "...",
    $campaign: "...",
    $adGroup: "...",
    $ad: "...",
    $keyword: "...",
    $creative: "..."
  });

I would like to know the correct mapping from UTM attributes to these RevenueCat campaign data attributes please. I could not find anything in the docs on this.
