How to reconnect to existing session in appium server

appium_webdriver.py

from typing import Any, Dict, List, Optional, TypeVar, Union
from appium import webdriver

class AppiumWebDriver(webdriver.Remote):
  def __init__(
    self,
    session_id: None,
    command_executor: str = 'http://127.0.0.1:4444/wd/hub',
    browser_profile: str = None,
    proxy: str = None,
    keep_alive: bool = True,
    direct_connection: bool = False,
  ):

    desired_capabilities = dict(
      # define your capabilities here
    )

    self._session_id = session_id
    self._capabilities = desired_capabilities
    
    super().__init__(
      command_executor, desired_capabilities, browser_profile, proxy, keep_alive, direct_connection
    )

  def start_session(self, capabilities: Dict, browser_profile: Optional[str] = None) -> None:
    if self._session_id in (None, False, 0):
      super().start_session(capabilities, browser_profile)
      return

    """Connects with existing session with specified session id."""
    self.session_id = self._session_id
    self.w3c = True
    self.command_executor.w3c = self.w3c

this is to save precious time reinitializing new session by appium

# main.py
from .appium_webdriver import AppiumWebdriver

if __name__ == "__main__":
  driver = AppiumWebdriver() # for new session
  sessionid = driver.session_id
  sessionurl = driver.command_executor._url
  
  # later reconnect like follows:
  driver = AppiumWebdriver(sessionid, sessionurl)
