To change or customize your application, you need to edit the code and you have to know Laravel, HTML, and CSS

You will get the view files to root/resources/views directory

3. Please check that you’ve set SMTP credential at .env file located at the root.

However, you can customize anything if you know laravel, it’s really easy to edit the code if you don’t know the laravel, then you might be confused almost everywhere.
