[RSS Feed/News] Proper way to remove the whatsnew button from nav bar?

[XenForo]

I tried the following template modification, but it looks ineffective:

Templage: PAGE_CONTAINER
Find (regex):
Code:

<a href="{{ link\('whats-new'\) }}"(.|\n)*class="(.|\n)*p-navgroup-link--whatsnew(.|\n)*"(.|\n)*<\/a>
Replace with nothing.

Is there any mistake(s) above?
