Make migration from code

So I'm trying to create a migration from one of my model's with it's model name (building a CMS so every time they build it, it will create the database fields (if they've changed from the last migration).

This is what I have so far:

$name = $this->getClassName();
        
$command = $this->artisan('make:migration create_' . strtolower($name) . '_table');
dd($command);


/****** METHOD IN CLASS ********/
/**
 * Call artisan method
 */
protected function artisan($command, array $args = [])
{
    $process = new Process('cd ' . base_path() . ' && php artisan ' . $command);
    return $process->run();
}

My question is after the migration is created, is there a way to edit it within Laravel? Or will I have to do some weird opening of the file, editing the up and down methods?

Thanks for any help!
