Is there a way to use IMAGE formula without rendering the @ character?

[vdariel]

I'm trying to generate a simple Export with an image using this code

class SimpleExport extends BaseExport implements WithEvents, FromCollection, WithColumnFormatting, WithStyles, WithColumnWidths
{
    use RegistersEventListeners;

    public function __construct()
    {
    }

    public function title(): string
    {
        return 'Simple Report';
    }

    public function collection(): Collection
    {
        $collection = new Collection();

        $collection->push(['1', '2', 'https://fastly.picsum.photos/id/760/50/100.jpg?hmac=tHENtAvtNTR5CaRI1pcqmb5AcFMywXgyqTxVJwEdeIw']);
        $collection->push([' ', ' ', ' ']);
        $collection->push([' ', ' ', ' ']);

        return $collection;
    }

    public function columnFormats(): array
    {
        return [];
    }

    public function styles(Worksheet $sheet): array
    {
        return [];
    }

    public function columnWidths(): array
    {
        return [];
    }

    public static function afterSheet(AfterSheet $event)
    {
        $event->sheet->setCellValue('B2', '=IMAGE(A3)');
        $event->sheet->setCellValue('C3', '=SUM(A1, B1)');
    }
}

and in my Controller this code:

Excel::store(new SimpleExport(), 'simple.xlsx', 'local');

The excel file is generated successfully but in the cell B2 the value is =@image(A3), I don't know where is coming from the @
Also I tested setting the value of that cell using the URL like this

$event->sheet->setCellValue('B2', '=IMAGE("https://fastly.picsum.photos/id/760/50/100.jpg?hmac=tHENtAvtNTR5CaRI1pcqmb5AcFMywXgyqTxVJwEdeIw")');

And I got the same result.

I set the format of the cell to NumberFormat::General, I added the formula inside the styles method, I used events and nothing
The Excel file looks like this

The second formula SUM works fine and doesn't have the @ character.

I'll appreciate any help you can give me. Thanks in advance
