Registering User with Laravel Passport

Question

I set up password grant (it's backend for an app). Now, I can send a post request to oauth/token and it works on Postman. However, what if I want to register user from the api too?

I understand I can use current /register route, however, then will I need to redirect the user back to the login page and he logs in again with his credentials?

Or in the RegisterController, in registered() function, should I do I redirect to the oauth/token route? (For this, please note that I am sending, all the 5 data in 'x-www-form-urlencoded' and it seems to work. However, do I need to separate some in headers? It's blurry for me, so just wanted to ask when I have the chance).

Or should I add something in the oauth/token method like this guy? Actually, I tried to catch the posted $request data on AccessTokenController@issueTokenmethod inside library, however I couldn't figure out how to manipulate the parsedBody array. If I trigger my register function from the actual library, how would I know if it's register or login?

Maybe I am missing out some information, but I couldn't find anything based on this topic. What is the proper way of handling registering user in Passport?

Update: Accepted answer shows the 'register' cycle; and below it I have added 'login' and 'refresh token' implementations. Hope it helps :)

In your API create route as

Route::post('register','Api\UsersController@create');

And in UsersController create method create()

function create(Request $request)
{
    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $request
     * @return \Illuminate\Contracts\Validation\Validator
     */
    $valid = validator($request->only('email', 'name', 'password','mobile'), [
        'name' => 'required|string|max:255',
        'email' => 'required|string|email|max:255|unique:users',
        'password' => 'required|string|min:6',
        'mobile' => 'required',
    ]);

    if ($valid->fails()) {
        $jsonError=response()->json($valid->errors()->all(), 400);
        return \Response::json($jsonError);
    }

    $data = request()->only('email','name','password','mobile');

    $user = User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => bcrypt($data['password']),
        'mobile' => $data['mobile']
    ]);

    // And created user until here.

    $client = Client::where('password_client', 1)->first();

    // Is this $request the same request? I mean Request $request? Then wouldn't it mess the other $request stuff? Also how did you pass it on the $request in $proxy? Wouldn't Request::create() just create a new thing?

    $request->request->add([
        'grant_type'    => 'password',
        'client_id'     => $client->id,
        'client_secret' => $client->secret,
        'username'      => $data['email'],
        'password'      => $data['password'],
        'scope'         => null,
    ]);

    // Fire off the internal request. 
    $token = Request::create(
        'oauth/token',
        'POST'
    );
    return \Route::dispatch($token);
}

And after creating new user, return access token.
