Sanctum - How to allow api from ANY logged user?

i've a webapp with a single page made in vue, because it's requiring highly complicated interaction flows from users into the page.

Here my user of Laravel is already loged in.

I am using sanctum, (because I'm using backpack for laravel).

I ask you if there is a simple way to allow any logged user to be anthenticated and authorized to call any api.

we have this example route

Route::middleware('auth:sanctum')->get('/user', function (Request $request) {
    return $request->user();
});

In my page, using axios, I try to simply call axios.get('/user') but it returns me 'unauthorized'

I am doing api calls from same domain of webapp (so same domain of api)

Also, I added in the bootstrap.js file this line

windows.axios.defaults.withCredentials = true;

What is missing? As far as I know, every get send also all the cookies of the same domain to the server. So I expect Laravel can detected as logged the user. Why doesn't it happens?
