Showing values in labels or legend without needing user interaction

Hello and thanks for reading.

As title suggest, i need a way of showing values for visualisations (mainly pie & bars charts), without mouse hovering to show the tooltip.
My issue is very similar to this topic, as i, too, am using almost exclusively term aggregations.
I understand this is quite a mess for little QoL but am willing to contribute to solve my issue.
I spend quite some time on the kibana github but couldn't find any label-related stuff anywhere, and therefore i really don't know where to start...

If the UI allows it, the values are displayed on pie charts with a legend when enabled. This is a recently added feature so it might not be available on older versions.

Thank you for your answer.
Which version starts supporting this feature ? Couldnt find changelogs for minor releases.
