Registering User with Laravel Passport

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 :)

Reading this while Laravel 6 has recently been deployed, my solution for this is as following.

When you've followed the steps defined in Laravel's passport documentation and you added the HasApiTokens trait to the User model, you can call a createToken function on your user entities.

Also, in your RegisterController there's a registered function from the RegistersUsers trait that you can implement which is called when a user is successfully registered. So you could implement this as following:

protected function registered(Request $request, User $user)
{
    $token = $user->createToken('tokenName');

    return response()->json([
        'user' => $user,
        'token' => $token->accessToken,
    ]);
}

See the register function in the RegistersUsers trait for more information about the registration cycle..
