Log out with Spotipy library

Question

I'm trying to write an app, that will allow people to login and get access to their playlists. But I'm having a problem when I'm trying to log out from account of previous user: It simple stays with the same access_token and have access to previous account. How can I fix it?

import spotipy
import os
from spotipy.oauth2 import SpotifyOAuth

username = 'user'
scope = 'playlist-read-collaborative playlist-read-private playlist-modify-public playlist-modify-private'

auth_manager = SpotifyOAuth(client_id = CLIENT_ID',
                            client_secret='CLIENT_SECRET', username=username,
                            redirect_uri='http://google.com/', scope=scope)
sp = spotipy.Spotify(auth_manager=auth_manager)
cache_path = f".cache-{username}"
if os.path.exists(cache_path):
    os.remove(cache_path)

if auth_manager.get_access_token() is not None:
    print(f"User {username} is logged in.")

    user_info = sp.current_user()
    print(f"User ID: {user_info['id']}")
else:
    print(f"User {username} is not logged in.")


def get_playlists():
    user = sp.current_user()
    current_playlists = sp.user_playlists(user['id'])['items']

    playlist_with_items = {}
    for playlist in current_playlists:
        playlist_with_items[playlist['name']] = []
        for pl in sp.playlist_items(playlist['id'])['items']:
            playlist_with_items[playlist['name']].append(
                pl['track']['album']['artists'][0]['name'] + '-' + pl['track']['name'])

    return playlist_with_items


def parser(link: str):
    i = 0
    playlist_id = ''
    while i < len(link):
        if link[i:i + 17] == 'open.spotify.com/':
            i += 17
            if link[i] == 'p':
                i += 9
                while i < len(link) and link[i] != '/':
                    playlist_id += link[i]
                    i += 1
                if playlist_id:
                    return playlist_id
                else:
                    raise ValueError("Playlist ID not found")
            else:
                break
        i += 1
    raise ValueError("Invalid link")


def get_playlist_by_url(pl_id):
    current_playlist = sp.playlist_items(pl_id)
    playlist_with_items = []
    for track in current_playlist['items']:
        playlist_with_items.append(track['track']['album']['artists'][0]['name'] + '-' + track['track']['name'])
    return playlist_with_items


def search_create_add(query: list):
    uris = []
    needed_id = None
    for i in query:
        ur = sp.search(i)['tracks']['items'][0]['uri']
        uris.append(ur)
    print(uris)
    sp.user_playlist_create(user_info['id'], name='New_try')
    for playlist in sp.current_user_playlists()['items']:
        if (playlist['name'] == 'New_try'):
            needed_id = playlist['id']
    sp.playlist_add_items(playlist_id=needed_id, items=uris)
