Gutenberg Plugin: How to add custom item to color toolbar panel?

Hi,

I’m developing a Gutenberg block that supports “color” inside the block.json file. Right now supports color for text, background, and link.

Now, I need another value to apply color for an icon.

This is what I’m trying to achieve:

Is there a way to do it? Like, the component has a filter to add more items or something like that.

Thanks.
