What is the type of a React Icon ?

I have just started using react icons with Typescript in a mini project. however, I got confused about the type should I use for an icon property in a React component.

export const ShareButton = ({ icon }:any) => {
  const colorContext = useContext(RandomColorContext);
  return <StyledButton color={colorContext}>{icon}</StyledButton>;
};

I use ShareButton like this:

 <ShareButton>
              <FaTwitter size={16} color={`rgb(${colorContext})`} />
            </ShareButton>

As you see I enforced to use any to skip the error. What should I use instead of any?

Thank you.
