Passport and Auth::logout() produces an unexpected error

Question

I am using Laravel 6.7 with Passport to consume my own API. When I try to logout a user using Auth::logout(), I get the following error:

Illuminate\Auth\RequestGuard::logout does not exist.

I don't understand why I get such behavior. I haven't used any custom guards. My Auth.php as per the Passport Setup is as follows:

<?php

return [
    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'passport',
            'provider' => 'users',
        ],
    ],

This is my AuthenticationController.php where the logout code resides:

/**
     * --------------------------------------------------
     * Removes the identity of a users login session.
     * --------------------------------------------------
     * @param Request $request
     * @return MessageResource
     * --------------------------------------------------
     */
    public function logout(Request $request): MessageResource
    {
        if (Auth::check()) {
            Auth::user()->token()->revoke();
        }
        return new MessageResource(['message' => 'Logout request is successful.']);
    }

Is there any way to solve this issue? Any insights would be greatly appreciated. Thanks in advance.

Auth::logout() is for web guard.Here, you are using API guard so delete token of authorization it'll automatically logout from you application.

public function logout(Request $request)
{
    $request->user()->token()->revoke();
    //$request->user()->token()->delete(); for delete.
    //Auth::user()->token()->revoke(); same way as revoke user token
    return response()->json([
        'message' => 'Successfully logged out'
    ]);
}
