Project page in Portfolio - how do i change link of header logo

Site URL: https://5trainingbiotechandpharma.co.uk

Hi

I've set up a portfolio page as the landing page. How do I link the header logo on each project page to a different page (I don't want it to link back to my portfolio/landing page)?

I have no background on CSS.  But after reading posts and forums, I sort of have an idea to do this in Design - Custom CSS, then insert page ID.  However, the codes I've seen are for ordinary pages and do not work for a project page. 

Many thanks for your help.

Edit each project page >>> Add a Code Block (under project page title) >> paste this code

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
	$('.header-title-logo a').attr('href','https://beaverhero.com');
});
</script>

replace beaverhero with new url

Thank you tuanphan.  I've decided to make it simpler and just use image blocks instead of portfolio.
