Get user phone number in firebase cloud functions

I've written https.onCall firebase cloud function like

exports.sampleFunction=functions.https.onCall((data,context)=>{
console.log(context.auth.token.phoneNumber+" ***** "+context.auth.token.email+" ***** "+context.auth.token.name);
  return userTransaction.sampleFunction(data,context).then(function(message){
    console.log(message);
  })
});

I'm storing the user's phone number and can fetch phone number at client using

FirebaseAuth auth=FirebaseAuth.getInstance();
        FirebaseUser user=auth.getCurrentUser();
        user.getPhoneNumber();

When I'm calling this function, I can see that email and name is getting printed at firebase cloud functions logs but phoneNumber is undefined. How to get user phone number through context in firebase cloud functions?

So much easier:

exports.myFunction = functions.https.onCall((data, context) => {
    const phone = context.auth.token.phone_number;
})

The following, using admin.auth().getUser(uid) should work:

const functions = require('firebase-functions');
const admin = require('firebase-admin');
....

exports.sampleFunction = functions.https.onCall((data,context) => {

  return admin.auth().getUser(context.auth.uid)
    .then(userRecord => {
      const phoneNumber = userRecord.phoneNumber;
      console.log(phoneNumber+" ***** "+context.auth.token.email+"      ***** "+context.auth.token.name);   
      return userTransaction.sampleFunction(data,context)    //Not sure what this is doing, I just chained it with the previous and next then(s). Modify as necessary....
    })
    .then(message => {
      console.log(message);
      return { message: message };
    })

});

See the corresponding docs here and here. Note that getUser() returns a promise.
