Add formspree to shiny app hosted on shinyapps.io

Hi there,

is it possible to add a contact form like the one of formspree to a shiny app?

I was able to load the formspree html snippet using includeHTML

<!-- modify this form HTML and place wherever you want your form -->
<form
  action="https://formspree.io/f/your_token"
  method="POST"
>
  <label>
    Your email:
    <input type="email" name="email">
  </label>
  <label>
    Your message:
    <textarea name="message"></textarea>
  </label>
  <!-- your other form fields go here -->
  <button type="submit">Send</button>
</form>

But there was no repsone when clicking the send button. Is this per se not working on shinyapps.io?

OK, found this old answer that it propably won't work Shinyapps.io and the sendmailR package - #3 by MarkeD. But perhaps there is now a workaround available?!
