That will be a core WordPress widget. You would be better off asking about that in the WooCommerce forum. Please also note the parts I already mentioned though. That widget will only work on archives of products which can actually be filtered. Also note, that is completely separate from Avada. https://docs.woocommerce.com/document/woocommerce-widgets/
Regarding screenshots the best idea would be to use a tool to take a screenshot, upload that and then share the URL rather than embedding directly (most tools you can download take care of both aspects).
Please also note, you would not need 3 separate support licenses, only 1. You can also try the Facebook community for help in addition to the forum.
