How to painlessly change the entire content of a MailMessage in laravel?

Question

Laravel

I fill in the parameters of the letter, but unfortunately in the documentation I did not find all the sections of the letter that I need to fill out.

return (new MailMessage)
                    ->subject($this->emailText)
                    ->greeting('Здравствуйте!')
                    ->line($this->emailText.' сформирован.')
                    ->action('Скачать файл', url($pathToExcel))
                    ->salutation('С уважением, команда сервиса .....');

Here is what I was able to find how to fill. But there are two more extra fields that bother me.

How do I fill in the fields pointed to by the arrow painlessly?
I understand that the top text is taken from .env from the APP_NAME line
. But I need nothing to come out there at all.
Plus, in the footer of the letter, there is a text about what you need to download the attachment.
I found this text in the only place - in the file
vendor\laravel\framework\src\Illuminate\Notifications\resources\views\email.blade.php
But I won't go into the vendor folder and change something there. I would like to set it through the parameters, but I do not see the logic.
Tell me how this is done in general so as not to climb into the vendor.

Answer 1

The command
copies the email here
resources/views/vendor/mail
and can be changed as you like

It is possible to override the template with your own view method. Well, make your own based on the built-in
