[v5] legend positioning

[clmz]

how can I set the position of the legend below the chart, e.g. in v4:

chart.legend({
position: 'bottom-left',
})

but this (and many many more properties) don't work anymore and it seems that there's no doc for this?

futher:
What leads to a cropped itemLabel?

when my code is like this:

.legend('color', { itemLabel: 'Total', layout: 'flex', width: 1000, });
