How to anchor a page in a pdf document?

Question

PHP

Hello! I use the html2pdf library to generate pdf documents. There is a Link2 link in the attached image.

The PDF document has 6 pages. There may be a different amount, not the point.
Question: what needs to be written in HTML or PHP, so that by clicking on Link2, we get, for example, to page 4 of the document? That is, make a regular anchor like in HTML. Google turned up nothing

Answer 1

<a href="document.pdf#page=4">
