How to make exploded Pie Chart?

I am working with Plotly.js 2.5.1 (latest version as I am writing) and I would like to know how to make an exploded Pie Chart.
I have tried a workaround using marker.line.color and marker.line.width but the gap between each sector isn’t transparent (as you can see in this example https://codepen.io/pen/?template=oNwPgXE).
I’ve tried to set the opacity of my color to 0 but the gap just disapears.

Do you know a way to do it without setting the marker.line.color identical to the background color?
Thank you!
