Add FooGallery button not working in Elementor

I would like to add a FooGallery to either the carousel or text widgets in Elementor, but the “Add FooGallery” button just doesn’t do anything! Also, the FooGallery shortcode doesn’t work in the Elementor shortcode widget! I have successfully used the FooGallery widget in an Elementor page – all works fine. So Foo does seem to be compatible, but just not in these areas! Any ideas? Thanks
