Can I use the icon on my logo? What are the rules for this to be done?

Hello good afternoon!
I have a logo, on it I have an elephant icon (which I would like to change), so I went to the icons8 site and I really liked a model that is there.
I wonder if I can use it in my logo, how do I get rights to it?
