Question Compatible Unity versions for Unity Gaming Services Analytics

The FAQ says that version 2019.4 is the minimum for running Unity Game Services Analytics. However, on the documentation page for the new analytics package (com.unity.services.analytics, https://docs.unity3d.com/Manual/com.unity.services.analytics.html), the supported Unity versions section of the page excludes a few versions after 2019.4, including 2021.x.

Does this mean that Unity 2021.x versions are actually incompatible with Unity Game Services Analytics? Can I use com.unity.services.analytics in 2021.x somehow? Or can I use the Unity Game Services Analytics with the older analytics library, com.unity.analytics in Unity 2021.x? Or is it necessary to upgrade Unity to one of the supported versions?
