How can I change background of the chart?

I have created a chart in Power BI with plotlyjs and i was wondering how can i change my background color and make it transparent.

Thank you.

Have you tried:

paper_bgcolor: "rgba(0,0,0,0", //background color of the chart container space
plot_bgcolor: "rgba(0,0,0,0)", //background color of plot area

I believe the key here being the โ€œaโ€ within rgba, specifies โ€˜alphaโ€™ (4th digit), allowing control of opacity. red, green, blue, alpha.
