how to connect flet with PyDrive

[bobwatcherx]

I want to connect between flet and google drive so I can do crud files there. but the pydrive has its own server, namely http://localhost:8080 and a different flet port. and i register Authorized Url in google cloud with IP address from pyDrive which is http://localhost:8080 and i make code and first run . terminal asks to login in browser and my flet screen keeps loading non-stop. Is there a way or workaround for this problem?
I've also tried saving the token file so I don't log in again. but the flet keeps loading continuousl
my code

from flet import *
from pydrive.drive import GoogleDrive
from pydrive.auth import GoogleAuth
gauth = GoogleAuth()
# Try to load saved client credentials
gauth.LoadCredentialsFile("mycreds.txt")

if gauth.credentials is None:
    # Authenticate if they're not there

    # This is what solved the issues:
    gauth.GetFlow()
    gauth.flow.params.update({'access_type': 'offline'})
    gauth.flow.params.update({'approval_prompt': 'force'})

    gauth.LocalWebserverAuth()

elif gauth.access_token_expired:

    # Refresh them if expired

    gauth.Refresh()
else:

    # Initialize the saved creds

    gauth.Authorize()

# Save the current credentials to a file
gauth.SaveCredentialsFile("mycreds.txt")  

drive = GoogleDrive(gauth)

# # LIHAT SEMUA FILE
# file_list = drive.ListFile({'q': "'1XG2HCBD9vi7Ibcm7LbSvfmUVrJOk_nwA' in parents and trashed=false"}).GetList()
# for file1 in file_list:
#   print('title: %s, id: %s' % (file1['title'], file1['id']))

def main(page:Page):
	page.add(
		Column([
		Text("FLet DRIVE ",size=30,weight="bold")

		])
		)

flet.app(target=main)
