Setting a custom user verification link issue in laravel

I have been trying to send my users a custom verification email in laravel.

First I run this

php artisan make:notification SendRegisterEmailNotifcation

This has created a file called, SendRegisterEmailNotifcation.php inside my App/Notifications.

Then Inside my user controller's store method, I called that method after user insertion done.

Following is my store function,

public function store(Request $request)
    {
        request()->validate([
            'name' => ['required', 'alpha','min:2', 'max:255'],
            'last_name' => ['required', 'alpha','min:2', 'max:255'],
            'email' => ['required','email', 'max:255', 'unique:users'],
            'password' => ['required', 'string', 'min:12', 'confirmed','regex:/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{12,}$/'],
            'mobile'=>['required', 'regex:/^\+[0-9]?()[0-9](\s|\S)(\d[0-9]{8})$/','numeric','min:9'],
            'username'=>['required', 'string', 'min:4', 'max:10', 'unique:users'],   
            'roles'=>['required'],
            'user_roles'=>['required'],
        ]);

        //Customer::create($request->all());

        $input = $request->all();
        $input['password'] = Hash::make($input['password']);

        $user = User::create($input);
        $user->assignRole($request->input('roles'));

        //event(new Registered($user));
        $user->notify(new SendRegisterMailNotification());

        return redirect()->route('customers.index')
                        ->with('success','Customer created successfully. Verification email has been sent to user email.  ');
    }

And this is my SendRegisterMailNotification.php

<?php

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
use Illuminate\Notifications\Notification;

class SendRegisterMailNotification extends Notification
{
    use Queueable;

    /**
     * Create a new notification instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Get the notification's delivery channels.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function via($notifiable)
    {
        return ['mail'];
    }

    /**
     * Get the mail representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return \Illuminate\Notifications\Messages\MailMessage
     */
    public function toMail($notifiable)
    {
        return (new MailMessage)
                    ->line('The introduction to the notification.')
                    ->action('Click Here to Activate', url('/'))
                    ->line('Thank you for using our application!');
    }

    /**
     * Get the array representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function toArray($notifiable)
    {
        return [
            //
        ];
    }
}

Now this process works well, newly created users are receiving their emails.

But the issue is

Normally in laravel activation link has a certain format and once the user hits on the button user's account get activated and store verified date time in the user table, also the link expires in 60 minutes..

Sample verification link,

http://test.site/email/verify/22/3b7c357f630a62cb2bac0e18a47610c245962182?expires=1588247915&signature=7e6869deb1b6b700dcd2a49b2ec66ae32fb0b6dc99aa0405095e9844962bb53c

But in my case I am struggling to set that activation link and the process properly, How can I do that using the above customized email?
