Is there any documentation about cfz_

For example, i can see this data from the cookie:

{
  "egnm_engagementDuration": {"v": "0", "e": 1772561008328},
  "egnm_engagementStart": {"v": "1741025008328", "e": 1772561008328},
  "egnm_counter": {"v": "2", "e": 1772561008328},
  "egnm_session_counter": {"v": "2", "e": 1772561008328},
  "egnm_ga4": {"v": "3ba93466-8729-4e58-96ff-09d2c6233ca2", "e": 1772561008328},
  "egnm__z_ga_audiences": {"v": "3ba93466-8729-4e58-96ff-09d2c6233ca2", "e": 1772556765275},
  "egnm_let": {"v": "1741025008328", "e": 1772561008328},
  "egnm_ga4sid": {"v": "417825486", "e": 1741026808328}
}

{
  "egnm_engagementDuration": {"v": "0", "e": 1772561008328},
  "egnm_engagementStart": {"v": "1741025008328", "e": 1772561008328},
  "egnm_counter": {"v": "2", "e": 1772561008328},
  "egnm_session_counter": {"v": "2", "e": 1772561008328},
  "egnm_ga4": {"v": "3ba93466-8729-4e58-96ff-09d2c6233ca2", "e": 1772561008328},
  "egnm__z_ga_audiences": {"v": "3ba93466-8729-4e58-96ff-09d2c6233ca2", "e": 1772556765275},
  "egnm_let": {"v": "1741025008328", "e": 1772561008328},
  "egnm_ga4sid": {"v": "417825486", "e": 1741026808328}
}

but it's unclear what each of the keys within the encoded json structure represent or how they specifically would map to google analytics api

i see some of the ga4 cookie values stored in cfz_google-analyticsv4 and decoding it allows me to see what appears to be the client id and session id but it looks like the measurement id is missing... ga<ContainerId> is missing also i am guessing that the client id is the uuid value... just i guess wondering if cloudflare has the components of the cookie document some where it would be very helpful
