I have that error in SonarQube: Remove the declaration of the unused 'Ico' variable.

And thats my code:

const ReactPage = (props) => {
    const {nomeCLasse} = props
    const icon = {};
     icon[opcaoAvaliacao.Satisfeito] = InsertEmoticonRoundedIcon;
     icon[opcaoAvaliacao.Neutro] = SentimentSatisfiedRoundedIcon;
    
     const render = () => {
        const Ico = icon[nomeClasse];
        return <Ico className={`iconeDescricao${nomeClasse}`} />;
      };
}

When I render this way the sonar gives me an error on line 5(const Ico = icon[nomeClasse]).

How do I render an icon in a different way than this with this icon dictionary?
