how to returning array $catatan and get the return array value on ProductController ?

<?php

namespace App\Imports;

use App\Category;
use App\Label;
use App\Product;
use App\SubCategory;
use Illuminate\Support\Collection;
use Maatwebsite\Excel\Concerns\ToCollection;
use Maatwebsite\Excel\Concerns\WithStartRow;

class ProductImport implements ToCollection, WithStartRow
{
    /**
     * @return int
     */
    public function startRow(): int
    {
        return 2;
    }
    
    /**
    * @param Collection $collection
    */
    public function collection(Collection $collection)
    {
        // return "asdad";
        foreach ($collection as $row) {
            $product = Product::where('number', $row[0])->first();
            $new = false;
            if ($product == null) {
                $new = true;
                $product = new Product();
                // $product->sku = $row[0];
            }
            $catatan = [];
            if ($new == true) {
                if (isset($row[1])) {
                    $product->name = $row[1];
                } else {
                    $catatan[]['message'] = "Kolom nama kosong, data baru tidak disimpan" + ($row[0] ? "SKU : " + $row[0] : "" );
                    continue;
                }
    
                if (isset($row[2])) {
                    $product->stock = $row[2];
                } else {
                    continue;
                }
            } else {

            }
            
            $product->save();
        }
    }
}

ProductController method Import

public function importProduct(Request $request)
    {
        $request->validate([
            'excel' => 'required',
        ]);

        $productImport = new ProductImport();
        Excel::import(new ProductImport, $request->excel);
        return ResponseAPI($productImport);
    }
