I try to bake migrations migration_snapshot in the plugin using another connection

• Have two db on same server and setup in app.php (default, forum)

• I can bake migrations snapshot or diff for both connection in main migrations folder, example
  bin/cake bake migration_snapshot Forum --connection forum

• But if I try to bake migrations snapshot or diff in plugin (backed forum plugin) with 'forum' connection, then bake create migrations file with empty up and down methods

bin/cake bake migration_snapshot Forum --plugin Forum --connection forum

<?php
declare(strict_types=1);

use Migrations\AbstractMigration;

class Forum extends AbstractMigration
{
    /**
     * Up Method.
     * ...
     */
    public function up()
    {
    }

    /**
     * Down Method.
     * ...
    */
    public function down()
    {
    }
}
