Cognito Federated user logout

For cognito user - Using Amplify I was able to login using

await Auth.signIn(this.email, this.password);

And logout using:

Auth.signOut();

For federated user - Using Amplify I was able to login using

await Auth.federatedSignIn({ customProvider: 'customProviderName' });

But logout doesnt support using:

Auth.signOut();

How can I signout federated user, so that when I try to login again, it ask my permission to login ?
