can’t find oceanWP widgets

Hi Everyone! I’m trying to get my head around the latest oceanWP… I want to create a custom header with elementor but I can’t find the nav widgets… Apparently, it’s in the oceanwp widgets, but they don’t show up! I installed the oceanwp theme, the “ocean extra” widget… And in the oceanwp panet > elementor widgets, there is a link that send me to a “freemium.com” where I have to add my (local) website.

I’ve got this message: “A website will be automatically added to this list once you install one of the products from the download section on your site and activate the license key.”

I don’t get how it’s working…

Couls you help me? thanks in advance!!!
