custom export word

I use this code for custom export of a PDF. I want to do the same thing with word but I don’t know how. I use phpmaker2024 and in the documentation it is specified that it does not work with export to word$doc - The object of the export class. You can set the properties of the object. The content of the export document is $doc->Text (except PhpSpreadsheet/PHPWord).how can I do custom export to word in phpmaker2024 without using external libraries?

public function rowExport($doc, $rs)
    {
    
        if ($this->isExport("pdf")){
            $idrapp=$this->idrapporto->CurrentValue;
            $rappo=testouffcompdf($idrapp,1);
            $testo=$rappo;
            $doc->Text .=  $testo; 
        }
