Migrate to a certain file

Let's say I have 10 migrations files in the folder "App/Database/Migrations and everyone is migrated. Now I like to rollback to the migration nr 7. How can I do that from a controller in CI4?
In CI3 I ran

Code:

$this->migration->version($timestamp);

I have problem finding any function that rollbacks migrations the way I want:
Method regress() seems to work with batches and groups. I have group 'default' and batch '1' in all my files, so that's not for me.
Method force() might work, but how do I pass in the namespace as the second argument? force('App\Database\Migrations\Add_something,)
The following ugly script throws the error "Migration file not found":

PHP Code:

<?php namespace App\Controllers;

class Migrate extends \CodeIgniter\Controller
{
    public function index()
    {
        // Find latest migrated file
        $db = \Config\Database::connect();
        $query = $db->query('SELECT * FROM migrations ORDER BY id DESC LIMIT 1');
        foreach ($query->getResult() as $row)
        {
            $latest =  $row->version;
        }

        // Display all migrations files with links to method "force"
        $migrate = \Config\Services::migrations();
        $files =  $migrate->findMigrations();
        echo "Migrations (to keep order, only migrate one step up/down at a time. I will restrict links someday):<br>";
        foreach ($files as $file) {
            echo $file->path;
            echo '<a href="/migrate/force/'.$file->path.'">Migrate this file</a>';
            if($file->version == $latest)
                echo ' LATEST';
            //dx($file);
            echo '<br>';
        }
    }

    public function force($path){
        $migrate = \Config\Services::migrations();
        $migrate->force($path,'App\Database\Migrations');
        return redirect()->to('/migrate');
    }


} 


FYI The above controller results in a view like this:

"Migrations (to keep order, only migrate one step up/down at a time. I will restrict links someday):
