Laravel API middleware - How to retrieve current user without requiring authentication

I have the following route in my routes/api.php

Route::get('/games/{game}', 'GamesController@show')->name('api.games.show');

On client side, I already included Authorization bearer token header in every AJAX request.

How can I retrieve the value of the user associated with the token throught $request->user() without having to require authentication (without having to use ->middleware('auth:api'))
