How to run hcaptcha callback function

Question

I'm trying to run the callback function for the hcaptcha but it keeps giving me the null (reading 'appendChild') error, If anyone has any other suggestions, I'd appreciate it.

import os
import threading
import time

import nopecha
import undetected_chromedriver as uc
import tkinter as tk

def solvehCaptcha():
print("başlatıldı!")
nopecha.api_key = '\*'

    # Call the Token API
    token = nopecha.Token.solve(
        type='hcaptcha',
        sitekey='b4c45857-0e23-48e6-9017-e28fff99ffb2',
        url='https://nopecha.com/demo/hcaptcha#easy',
    
    )
    
    
    print(token)
    
    browser.execute_script(f'''                                                                                                                                                             
    document.querySelector('[id^="h-captcha-response-"]').innerHTML = "{token}"                                                                                                             
    ''')
    js_script = f"""
              let captchaElement = document.getElementById('captcha')
              let inputElement = document.createElement('input');
              inputElement.setAttribute('type', 'hidden');
              inputElement.setAttribute('name', 'response_token');
              inputElement.setAttribute('value', "{token}");
              captchaElement.appendChild(inputElement)
    """
    browser.execute_script(js_script)

options = uc.ChromeOptions()
options.set_capability("detach", True)

browser = uc.Chrome(options=options)

browser.get('https://nopecha.com/demo/hcaptcha#easy')

root = tk.Tk()

root.geometry("300x300")

btn = tk.Label(root, text="Başlat", bg="Black", fg="white")
btn.pack(side="top", anchor="center")
btn.bind("\<Button-1\>", lambda e: threading.Thread(target=solvehCaptcha).start())

root.mainloop()

Error result:

I want to make the hcaptcha callback without submit button, but I get error: Cannot read properties of null (reading 'appendChild')
