Can't see the details on the video - all too small to read.. but it looks like a custom CSS addition which I did in the end anyway ("Additional CSS", and which works OK).
a {color:#ff0000;}
a:hover {color:0000ff;}
But really, link, link hover and link visited colors should be an option from somewhere within Elementor. No big deal though

Thanks buffalobooster! Quick work...
