How to deny access to some requests in api in laravel?

Question

Laravel

Hello!
Maybe I do not quite understand, but how can I deny access to some api requests.
Those. let's say I have this api.php

Route::apiResource('products',ProductsController::class);
Route::apiResource('cart',CartController::class);
Route::apiResource('admin',AdminController::class);

And yet I can use api admin through the same postman. To deny access to this api, I must hang an intermediary on it, which will check whether the user is authorized as an admin?
