js event triggered by CAPTCHA completion

is there a javascript event that is triggered when a CAPTCHA has successfully been completed?

i want to use this event to automatically submit the form on CAPTCHA completion, but i can't find anything in the module code that looks like what i need.

any ideas?

(note: i am using Cloudflare Turnstile https://www.drupal.org/project/turnstile → as my CAPTCHA, if the event would be originating from there instead, that's fine, i just thought there might be something in the CAPTCHA wrapper as well, and that would be better, in case i switch from Turnstile to some other captcha module plugin.)
