filter everything widjet not showing in wordpress

hi im trying out filter everything so its the free version and i cant find the widget anywhere? i created a simple product filter set with only product filter by cat,and price iv then published it and when i try to find it to put it into a container its now where to be found?iv tried using a short code widget and that seems to not be working either?im using elementor as a editor, im on the latest version of wordpress im using google chrome as a browser ,every-time i try to get this plugin working it never does i tried for a week about a month ago nothing worked like all the videos online it seems pretty simple but not for me? im on a mac latest version of osx iv also have woobewoo filter installed and it works wonderfully not sure why your plugin always has problems?
