Using view_cell - I am not clearly getting how to do it

So do you mean like this?

PHP Code:

<?php

namespace App\Cells;
use CodeIgniter\View\Cells\Cell;

class BlockCell
{

    private $blockModel;

    public function getBlock($bloc_name)
    {
        $this->blockModel = model('BlockModel');
        
        return $this->blockModel->asArray()
            ->where(['bloc_name' => $bloc_name])
            ->first();
    }

} 


Then I run into

PHP Code:

CodeIgniter\View\Cell::renderSimpleClass(): Return value must be of type string, array returned
