Following this documentation: Firestore Docs

my code:

import { setDoc, doc } from "firebase/firestore";

const sendMessage = (e) => {
    e.preventDefault();

    try {
      await setDoc(
        doc(db, "messages", "test"),
        {
          firstName: firstName,
          lastName: lastName,
          email: email,
          phoneNumber: phoneNumber,
          message: message,
          created: Date.now(),
        }
      );
      console.log("Document written with ID: ", docRef.id);
    } catch (e) {
      console.error("Error adding document: ", e);
    }

I'm using react, and getting this error: "Unexpected reserved word 'await' "
