Notification with markdown not work

I've a custom command that generate a report and at end, send a Mail to admin.

        $lines = $r->markdown;

        Mail::to(['[email protected]'])->send(new VersionSchemaReport($lines));

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class VersionSchemaReport extends Mailable
{
    use Queueable, SerializesModels;

    public $lines;


    public function __construct($lines)
    {
        $this->lines = $lines;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->markdown('mail.dbschema.report');
    }
}

blade

@component('mail::message')
# Report DBSchema change for iRedMail Databases

@foreach ( $lines as $line )
    {{ $line }}
@endforeach
