Your linked article (the official source from Google) states "November 2021" [1], which by date would correspond to API Level 32 aka. Android 12.1.
Android 12.0 might also have the feature backported on some devices, according to some reports such as seen in the issue report for the feature [2].
Finally, the feature has apparently not been backported to Android 10 or 11, according to a blog post I found about this topic [3].
