How to optimize multiple reCaptchas on the same page?

Question

JavaScript

Hello.
We have 6 forms on the site on one page. Now the task is to connect recaptcha to them. I did everything, but the page takes an average of 20 seconds to load, loading a repcha for each form.
After loading everything works, but the loading time just kills.
So two questions:
1. How to optimize recaptcha?
2. Is there a better way to protect forms from spam than Invisible reCaptcha?

Answer 1

The problem is that you load the captcha right away, even if you don't need it.
Start loading captcha when opening a modal with a form, or when the user starts filling out the form.
