Hello ! Need Help

Hello everyone ! I created "componentDidUpdate()" for check my localStorage. If I receive a token, my state change but it's didn't work ...

componentDidUpdate(prevState) {

    const propsConnexion = this.props.connexion;
   // const connexionFalse = this.props.connexion === false;
   //const connexionTrue = this.props.connexion === true;
    if(propsConnexion !== prevState.propsConnexion){

           if(localStorage.getItem("jwt") !== null) {

               this.props.connexion(true)
               console.log(this.props.connexion)

            }

           else{
              console.log( this.props.connexion)
               this.props.connexion(false)
            } 

        }      
}
