Type issue of ref using EmailJS and Typescript

I'm new to React and I use the Astro framework. I would like to add a contact form to my landing page and to do so I use the EmailJS service. I tried to get the example in documentation of EmailJS for React and adapt it to Typescript but I can't understand this error:

Type '{ children: any[]; ref: MutableRefObject<string | HTMLFormElement>; onSubmit: (e: any) => void; }' is not assignable to type 'FormHTMLAttributes'. Property 'ref' does not exist on type 'FormHTMLAttributes'.

My code in following:

import ContentSection from "~/components/content-section.astro";
import React, { useRef } from 'react';
import emailjs from '@emailjs/browser';

export const ContactUs = () => {
  const form = useRef() as React.MutableRefObject<string | HTMLFormElement>;

  const sendEmail = (e: any) => {
    e.preventDefault();

    emailjs.sendForm('YOUR_SERVICE_ID', 'YOUR_TEMPLATE_ID', form.current, 'YOUR_PUBLIC_KEY')
      .then((result) => {
          console.log(result.text);
      }, (error) => {
          console.log(error.text);
      });
  };

  return (
    <form ref={form} onSubmit={sendEmail}>
      <label>Name</label>
      <input type="text" name="user_name" />
      <label>Email</label>
      <input type="email" name="user_email" />
      <label>Message</label>
      <textarea name="message" />
      <input type="submit" value="Send" />
    </form>
  );
};
