I'm basically having an issue where the user can sign in without verifying their email address (clicking the link sent to their email). My code currently looks like this & every time I enter "isEmailVerified()" it tells me that no such function exists.

    const fbuilds = [];
    const frooms = [];
    clearErrors();
    fire.auth().createUserWithEmailAndPassword(email, password)
    .then((userCredential) => {
      userCredential.user.sendEmailVerification();
      alert('Please follow the link sent to your email address to verify your account.')
      fire.auth().signOut();
    })
    .catch((err) => {
      switch (err.code){
        case "auth/email-already-in-use":
        case "auth/invalid-email":
          setEmailError(err.message);
          break;
        case "auth/weak-password":
          setPasswordError(err.message);
          break;
      }
    });

and my auth listener function looks like this:

    fire.auth().onAuthStateChanged((user) => {
      if(user){
        if (user.isEmailVerified()){ //user.emailVerified
          clearInputs();
          setUser(user);
        }
      } else {
        setUser("");
      }
    });
  };
