How to select same repeated item that is present on all pages in draw?

So, this watermark text/link is present on every page of a pdf. How can I select them all and delete at once?

In a Draw file, repeating objects are commonly placed on the master page. Link to online help.

That master page may not exist or behave as expected when you are working on a PDF. Generation of PDF files commonly “flatten” the file structure. Objects retain their visual formatting only.

Search on the internet using pdf watermark delete - there are some (online and offline) tools which could do. As @keme stated the pdf file could be flattened and LibreOffice would handle the watermark as single objects of each page containing it…

Thanks for the help. I got this link- How to Remove all Hyperlinks in PDF.
I tried to do the recommended method to flatten the pdf. It didn’t help fully.
There are 2 kinds of hyperlinks in my pdf. One is basic text of website address with link. Other is watermark on every page with link. Also the pdf is not made of text, but of images of text.
Flattening removed link from watermark but considered watermark as image which earlier appeared as objects in Draw. Thats what @keme said. Also image of each page got split into 4. My file is too big to work on online. Thanks for help anyway.
