The getToken() call is asynchronous, and so it returns a promise. That's the structure your console.log actually outputs.

To get the actual value from a promise, you have to hook its then() callback, same as you already do for getToken().

So, this would work:

const fcmtoken = messaging()
  .getToken()
  .then((mainToken) => {
    return mainToken;
  });

fcmtoken.then((token) => console.log('fcmtoken:::', token));

Typically you'll want to dispatch the token when you've gotten it, meaning you'll call dispatch inside the callback, where you now do return mainToken. Just dispatch the token there, and don't return anything.
