How do you evaluate_js before DOM? (inject JS before DOM initializes)

[deb-its]

I am making a discord web client with vencord in it, and vencord script needs to load before DOM initializes, anyone know how to?

[deb-its]

Here's my code.

import os
import webview

appdata_path = os.getenv('APPDATA')

tiny_cord_path = os.path.join(appdata_path, 'Misscord')
storage_path = os.path.join(tiny_cord_path, 'Storage')

os.makedirs(storage_path, exist_ok=True)

def read_cookies(window):
  cookies = window.get_cookies()

  js_path = os.path.join(os.path.dirname(__file__), 'injection', 'inject.js')
  with open(js_path, 'r', encoding='utf-8') as js_file:
      js_code = js_file.read()
      window.evaluate_js(js_code)

  css_path = os.path.join(os.path.dirname(__file__), 'injection', 'inject.css')
  with open(css_path, 'r', encoding='utf-8') as css_file:
      css_code = css_file.read()
      window.load_css(css_code)

if __name__ == '__main__':
  options = {
      'url': 'https://discord.com/app',
      'width': 800,
      'height': 600,
      'resizable': True,
      'fullscreen': False,
      'easy_drag': True,
      'confirm_close': True
  }

  window = webview.create_window('Misscord', **options)
  
  webview.start(read_cookies, window, private_mode=False, storage_path=storage_path, debug=True)
