We are planning to use the icons from icons8.com in our project which is supposed to be open sourced. Is it OK to include the license statement in our license file instead of adding app link - Following two Icons by Icons8 (https://icons8.com/icons)
We request an attribution link in exchange for using our icons, as it helps more people discover us. It doesn’t have to be on your main page; an About page works just fine, for example.
You can check out this article for guidance on the best places to include the link.
