How to pass in a React icon as a prop and style it with Tailwind

Hello I'm trying to create a reusable react component that takes in an icon and I want to style said icon with a base style. I included some screenshots of what I have so far. I've been at this for a while, any help would be very much appreciated.

Set the type as React.ReactNode You could also use JSX.Element or React Element

I believe React.ReactNode is the most permissive

import { HomeIcon } from "@heroicons/react/20/solid";

interface IButtonProps {
  Icon: React.ReactNode;
}

const Button = ({ Icon }: IButtonProps) => {
  return <>{Icon} Click me!</>;
};

export default function Test() {
  return (
    <>
      <Button Icon={<HomeIcon className="text-lime-500" />} />
    </>
  );
}

There's something additionally needed for a type-safe usage. You can give the icon props as a generic, but then you need to make TypeScript happy by also checking whether this is a valid React element:

function Button(props: Props) {
  return (
    <button onClick={props.onClick}>
      {React.isValidElement<Props['icon']>(props.icon) ? (
        React.cloneElement<Props['icon']>(props.icon, {
          className: 'text-current',
        })
      ) : (
        <></>
      )}
    </button>
  )
}

function Button(props: Props) {
  return (
    <button onClick={props.onClick}>
      {React.isValidElement<Props['icon']>(props.icon) ? (
        React.cloneElement<Props['icon']>(props.icon, {
          className: 'text-current',
        })
      ) : (
        <></>
      )}
    </button>
  )
}
