Target class [currentTenant] does not exist Multi-tenancy

I am learning about Mulit-Tenancy in Laravel and am running into an issue and don't know exactly where to look to isolate the issue. I am following a tutorial https://www.youtube.com/watch?v=uvnvYzQ2fw0&t=187s and at 17 minutes into the video, I need to show the current Tenant by adding the {{app('currentTenant')}} line in the welcome.blade document. This trhows the error: Target class [currentTenant] does not exist I followed the documentation of the package I am using which can be found at https://spatie.be/docs/laravel-multitenancy/v1/basic-usage/automatically-determining-the-current-tenant where I add the 'tenant_finder' code to my multitenancy.php file located in the config folder. I am at a loss as to which code I need to modify to make this work. Any help would be greatly appreciated. I would also like to know if I can show any code and which peice to make helping me a bit easier but like I said, I am not sure what the offending or missing code is just yet. Thank you. In RouteServiceProvider.php, I have:

<?php

namespace App\Providers;

use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\RateLimiter;
use Illuminate\Support\Facades\Route;

class RouteServiceProvider extends ServiceProvider
{
    /**
     * The path to the "home" route for your application.
     *
     * This is used by Laravel authentication to redirect users after login.
     *
     * @var string
     */
    public const HOME = '/home';

    /**
     * The controller namespace for the application.
     *
     * When present, controller route declarations will automatically be prefixed with this namespace.
     *
     * @var string|null
     */
    // protected $namespace = 'App\Http\Controllers';

    /**
     * Define your route model bindings, pattern filters, etc.
     *
     * @return void
     */

    protected $namespace = 'App\Http\Controllers';

    public function boot()
    {
        $this->configureRateLimiting();

        $this->routes(function () {
            Route::prefix('api')
                ->middleware('api')
                ->namespace($this->namespace)
                ->group(base_path('routes/api.php'));

            Route::middleware('web')
                ->namespace($this->namespace)
                ->group(base_path('routes/web.php'));
        });
    }

    /**
     * Configure the rate limiters for the application.
     *
     * @return void
     */
    protected function configureRateLimiting()
    {
        RateLimiter::for('api', function (Request $request) {
            return Limit::perMinute(60)->by(optional($request->user())->id ?: $request->ip());
        });
    }
}

In my Welcome.blade.php, I am calling:

  <p style="color:white;">{{ app('currentTenant') }}</p>

In my Kernal.php, I am calling tenant as such:

	 'tenant' => [
            \Spatie\Multitenancy\Http\Middleware\NeedsTenant::class,
            \Spatie\Multitenancy\Http\Middleware\EnsureValidTenantSession::class,
        ],

If I am missing anything, please let me know.
