How to persist Firebase UserCredential object, so can use UserCredential.sendEmailVerification() function

Question

Firebase UserCredential object is generated when user logs in.

I want to use the function UserCredential.sendEmailVerification() to generate email to user if they have not previously verified their email address.....however I do not want to do this as soon as user has logged in. Instead I want to wait until they want to unlock some further functionality in the app....and only then do I want to send the verification email by running the UserCredential.sendEmailVerification() function.

Problem is....how do I persist the UserCredential object so that I have access to the sendEmailVerification() function everywhere in the app?

Is it possible to store as state?

You can get the signed in user at any time by using the code from the first snippet in the documentation on getting the current user:

firebase.auth().onAuthStateChanged(function(user) {
  if (user) {
    if (!user.emailVerified) {
      user.sendEmailVerification();
    }
  }
});
