How to make an included PDF page linked to an url?

I have a PDF title page included in the main document, using the pdfpages package, as shown in the MWE code below. I know that all the hyper links included in that page are lost in the process. But I’m now wondering if it’s possible to make the whole included title page as a clickable page, that would link to some URL. If so, how? I checked the pdfpages documentation and it wasn’t clear how we could do this. Any suggestion?

And if it’s possible, can we make the clickable title page to open several URLs at once?

Here’s a MWE code to play with:

documentclass[11pt,letterpaper,twoside]{book}
usepackage[T1]{fontenc}
usepackage{lmodern}
usepackage[total={6in,10in},left=1.5in,top=0.5in,includehead,includefoot]{geometry}
usepackage{amsmath}
usepackage{amsfonts}
usepackage{mathtools}
usepackage{tensor}
usepackage{pdfpages}
usepackage[unicode,colorlinks,linkcolor=blue,urlcolor=red,citecolor=blue,pdftitle={Title},pdfauthor={Name},pdfsubject={Subject},pdfkeywords={some words},pdfproducer={pdfLaTeX},plainpages=false,hyperindex=true,pdfpagelabels,linktocpage=true]{hyperref}

begin{document}

includepdf{TitlePage.pdf} % Not included in this example.  To be made as clickable to URL.

end{document}

documentclass[11pt,letterpaper,twoside]{book}
usepackage{pdfpages}
usepackage[unicode]{hyperref}

begin{document}
AddToShipoutPictureBG*{%
 AtPageLowerLeft{%
  href{https://www.latex-project.org/news/2020/07/22/latex-dev-2020-10-1b/}{rule{0pt}{textheight}hspace*{textwidth}}}}
includepdf{example-image-letter.pdf} %
