Metabox type color(picker), NATIVE method, who did it?

Question

WordPress

This is how text, number, checkbox are done in this article, by analogy, how to do color in the same way?
To make Iris appear, select a color in it and save the value.

Iris is built into the same customizer, so it should be possible.

I found this article on this subject, it seems to be it. https://madebydenis.com/adding-metaboxes-to-your-p...
I realized that I need to connect to the color-pickera api, scripts and styles through the admin panel.
But I don’t understand where this field is displayed in order to try it, and I still don’t understand how to transfer it to any of the hooks of the first article. In the sense of any hook that would display this beauty in the product tabs.
Maybe someone has already done this? Or someone with a trained eye.

It is the native method that is of interest. Maybe someone has already dug into the same thing as me.
