Custom Palette with my own icons

Hello,
I’ve noticed users asked a lot of questions about the Palette but unfortunately I couldn’t find the answer to my question.
I would like to add icons to my Palette but without using the icons given by bpmn but by using mine.
Is it possible ? And how can I do it ?

In advance thank you,

Maybe the nyan cat example will help you.

Yes thank you it’s totally what I was looking for !
