Laravel 5.6 render mails from custom path not default views path

I am trying to load blade templates from a different path than the default resource path. But I keep getting the error:

View [request.nlEmailTemplateTreatment] not found.

My path where the email template is stored:

root/storage/app/emails/request/nlEmailTemplateTreatment.blade.php

In the config/view.php I added this:

'paths' => [
    resource_path('views'),
    realpath(storage_path('app/emails/request'))
],

In my Mailable class I do this:

public function build()
{
    return $this->from('somerandomeemail@gmail.com')
                ->view('request.nlEmailTemplateTreatment');
}

I'm not sure why it's not working, I cleared cache with:

 php artisan config:cache
