I have a web app in reactjs that uses the Google login that is integrated into Appwrite for user login. I use Appwrite's createOAuth2Token() to login to their account. And I use createSession() to create a session within the Appwrite environment. To logout, I use deleteSession(). This approach of mine, however, only deletes the user's in process session within the Appwrite environment. It does not logout the user from their google account. I know this, because after clicking "logout", when the user tries to log back in, they are immediately signed in without being prompted to enter their Google credentials again, or to choose a different Google account from the list. I logged the details of the session, and I saw that providerAccessToken is an empty string. Since providerAccessToken is an empty string for Googe OAuth2 logins, I assumend that the session $id can replace it. However, it did not help. Google returns "Bad Request" and does not logout the user from Google.

export const deleteUserSession = async () => {
    const currentSession = await account.getSession('current');
    const accessToken = currentSession.$id;
    console.log('currentSession', currentSession);
    console.log('accessToken', accessToken);
    try {
        if (currentSession && accessToken) {
            await account.deleteSession(currentSession.$id);
            console.log('Session deleted successfully');
            await fetch('=' + accessToken, {
                method: 'GET',
                mode: 'no-cors',
            }); 
            console.log('LOGGED OUT SUCCESSFULLY.');
        }
        console.log('REDIRECTING TO /'); 
    } catch (error) {
        console.error('Error deleting the session:', error);
    }
}

My only issue with the current situation is that it doesn't allow others to log in if there already is a Google account logged in with that browser. It doesn't have that Google option which lists multiple accounts with an extra option of adding a new account if I delete gmail1's session. When I click on Login again, it logins with gmail1. The only time it lists the account with the option of adding a new account is when multiple accounts were previously logged in some of the Google services.
