Unlimited Elements for Elementor Pro with Free Elementor

Hi

I want to add circle infographic widget to my site but I have recently found that this widget is available in Unlimited Elements for Elementor PRO Version. Currently I am using basic version. Before buying pro version I want to ask if ‘Unlimited Elements for Elementor PRO’ will work with free version of Elementor? Or I have to buy Elementor Pro as well? Please reply asap.

Loads of Thanks!
