Same level categories in Woocommerce?

Question

I didn't find any resource explaining how to do this which seems really odd, so I'm asking the questions here.

I want to display, on the category page, the same level categories. I already display the sub-categories with the widget, but I cannot find a way to display the categories from the same level.

Is there any way to do that?

Thanks

I have tried a plugin called "X product filters" which offers this functionality, but it doesn't work
