How to add _token csrf globally on Laravel Inertia?

I have a project with Laravel Inertia and Vue Js. These day i have a problem with csrf token. I have already read the documentation here https://inertiajs.com/csrf-protection, so maybe i should add csrf token on every inertia request/response.

My question is, how to add this _token globally? So i dont need to one by one add token into my vue file, because its too much file.

My current script code on login.vue:

props: {
		errors: Object,
		session: Object,
		auth: Array
	},

	//define composition API
	setup(props) {
		//define form state
		const form = reactive({
			email: '',
			password: '',
		});

		//submit method
		const submit = () => {

			//send data to server
			Inertia.post('/login', {

				//data
				email: form.email,
				password: form.password,
				_token: props.auth.csrf
			});
		}

My HandleInertiaRequest (middleware):

<?php

namespace App\Http\Middleware;

use Illuminate\Http\Request;
use Inertia\Middleware;

class HandleInertiaRequests extends Middleware
{
	/**
	 * The root template that's loaded on the first page visit.
	 *
	 * @see https://inertiajs.com/server-side-setup#root-template
	 * @var string
	 */
	protected $rootView = 'app';

	/**
	 * Determines the current asset version.
	 *
	 * @see https://inertiajs.com/asset-versioning
	 * @param  \Illuminate\Http\Request  $request
	 * @return string|null
	 */
	public function version(Request $request): ?string
	{
		return parent::version($request);
	}

	/**
	 * Defines the props that are shared by default.
	 *
	 * @see https://inertiajs.com/shared-data
	 * @param  \Illuminate\Http\Request  $request
	 * @return array
	 */
	public function share(Request $request): array
	{
		return array_merge(parent::share($request), [
			//session
			'session' => [
				'status' 	=> fn () => $request->session()->get('status'),
				'success'   => fn () => $request->session()->get('success'),
				'error'    	=> fn () => $request->session()->get('error'),
			],
			//user authenticated
			'auth' => [
				'user'          => $request->user() ?   $request->user() : null,
				'permissions'   => $request->user() ? $request->user()->getPermissionArray() : [],
				'csrf' => $request->session()->token()
			],
			//route
			'route' => function () use ($request) {
				return [
					'params' => $request->route()->parameters(),
					'query' => $request->all(),
				];
			},
		]);
	}
}
