I don't need to rewrite the entire script, I need to be ignored by their detector.

I have written an autocomplete script on the site, its task is very simple. But the site added a captcha and now my bot is detected. I atteched this captcha and this source page. (1,2). The guy who wrote this script said this: "it's not about solving it, capmonster already solves it and sends the result back, But you can't send this result to anywhere".
This page chooses a city
- https://icp.administracionelectronica.gob.es/icpplus/index.html

For ReCaptca v3 i use anti-captcha.com and for v2(text) this capmonster.cloud/Dashboard (this more faster), best for speed is capmonster.

I don't need to rewrite the entire script, I need to be ignored by their detector. Please, I can’t take it right away, first run the script on your own and if you have solved a similar problem, write to me. Thank you!
