Adding Header Action to a resource

I see the option to add it on resource pages, but I just want it to appear on top next to the "New whatever" button. I tried getHeaderActions() on my WhateverResource.php and it doesnt seem to add the link.

Solution

I added this to the List:

Actions\Action::make('download')
->label(__('Download Plugin'))
->icon('heroicon-o-arrow-down-tray')
->url(function () {
return "/plugins/seed-manager.zip";
}),
