Laravel 8: Redirecting Forbidden Users To Their Respective Home Pages

Good Day

I'm new to laravel, and I'm building a website that has multiple users (Student, Supervisor, HOD). I am making use of the laratrust package to manage my users. If a student tries to access a url belonging to a supervisor, for example, laratrust throws an exception that says "USER DOES NOT HAVE ANY OF THE NECESSARY ACCESS RIGHTS". I would like to redirect the student back to their home page instead of this exception.

Here are my routes:

web.php

// Routes For Students
Route::group([
    'name' => 'student.',
    'prefix' => 'student',
    'namespace' => 'App\Http\Controllers',
    'middleware' => ['auth', 'role:student']
], function () {
    Route::get('home', 'StudentController@index')->name('student-home');
    Route::get('proposal', 'StudentController@proposal')->name('student-proposal');
    Route::get('thesis', 'StudentController@thesis')->name('student-thesis');
});

// Routes For Supervisors
Route::group([
    'name' => 'supervisor.',
    'prefix' => 'supervisor',
    'namespace' => 'App\Http\Controllers',
    'middleware' => ['auth', 'role:supervisor']
], function () {
    Route::get('home', 'supervisorController@index')->name('supervisor-home');
    Route::get('proposal', 'supervisorController@proposal')->name('supervisor-proposal');
    Route::get('thesis', 'supervisorController@thesis')->name('supervisor-thesis');
});

// Routes For HOD
Route::group([
    'name' => 'hod.',
    'prefix' => 'hod',
    'namespace' => 'App\Http\Controllers',
    'middleware' => ['auth', 'role:hod']
], function () {
    Route::get('home', 'hodController@index')->name('hod-home');
    Route::get('proposal', 'hodController@proposal')->name('hod-proposal');
    Route::get('thesis', 'hodController@thesis')->name('hod-thesis');
});

I have researched that in order to do this, I need to edit this specific part of the laratrust.php file:

    'middleware' => [

        'register' => true,

        'handling' => 'abort', // This needs to change to redirect

        'handlers' => [
            /**
             * Aborts the execution with a 403 code and allows you to provide the response text
             */
            'abort' => [
                'code' => 403,
                'message' => 'User does not have any of the necessary access rights.'
            ],

            // Redirect User To Their Respective Home Based On Their Role.
            'redirect' => [
                'url' => '/home',
                'message' => [
                    'key' => 'error',
                    'content' => ''
                ]
            ]
        ]
    ],

The home url is different based on the user type, so I want to know how I can check determine the type of user, then based on that assign their respective home url. Please let me know if you require more code or better explanation.
