Setting a plot non-visible by default but still appearing in the legend when loading?

[nanomonster]

In the ApexCharts documentation, there is a "hidden:" property available for that purpose (https://apexcharts.com/docs/hide-series-on-initial-render-in-a-multi-series-chart/) to disable some plots from showing when loading the graph, while leaving them actionable in the legend. It doesn't not seem to work in or to be implemented in HASS though? Anybody can help me with that?

I just found it! It escaped me while reviewing the documentation...
It's listed as an experimental feature in the doc:

I'm happy to report that it works for me...
