How to add hyperlink using templateprocessor (PHPWord Library) - laravel-5.5

Question

I want to replace email variable into a hyperlink using template processor and I have used two way to solved this issue but didn't work and here is our below code for replacing email variable into hyperlink but when I used setValue or setComplexValue function for replacement value then document is corrupted.
We have tried below two scenarios for adding hyperlink but didn't work for us.
1. First Way
$pw = new \PhpOffice\PhpWord\PhpWord();
$section = $pw->addSection();
$textrun = $section->addTextRun();
$textrun->addTextBreak(2);
$section->addLink('mailto:demo1#gmail.com?subject=DEMO','demo1#gmail.com', array('color' => 'FF0000', 'underline' =>
\PhpOffice\PhpWord\Style\Font::UNDERLINE_SINGLE));
$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($pw, 'Word2007');
$fullXml = $objWriter->getWriterPart('Document')->write();
$templateProcessor->setValue($var, $this->getBodyBlock($fullXml));
2. Second Way
$pw = new \PhpOffice\PhpWord\PhpWord();
$section = $pw->addSection();
$convertResult = 'demo1#gmail.com';
\PhpOffice\PhpWord\Shared\Html::addHtml($section, $convertResult, false,false);
$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($pw, 'Word2007');
$fullXml = $objWriter->getWriterPart('Document')->write();
$templateProcessor->setValue($var, $this->getBodyBlock($fullXml));
protected function getBodyBlock($string) {
if (preg_match('%(?i)(?<=<w:body>)[\s|\S]*?(?=</w:body>)%', $string, $regs)) {
return $regs[0];
} else {
return '';
}
}
