I am trying to add a donate link at the upper right in my MediaWiki website.

I have tried adding my donation URL to MediaWiki:Sitesupport-url and the text Donate to MediaWiki:Sitesupport just like what Wikipedia has but to no avail. I then tried adding

$wgHooks['SkinTemplateNavigation::Universal'][] = function ( $skinTemplate, &$links ) {
      $links['user_menu']['sitesupport'] = [
              'class' => '',
              'href' => '',
              'text' => 'Donate',
      ];
};

in the LocalSettings.php file but that just does nothing. I once got as far as adding the link to the drop down menu to logged in users but nothing for logged out visitors.

What I am trying to do is add a donate link that appears to the left of Create account link when logged out and next to the username link when logged in.

Using MediaWiki 1.43 and Vector 2022 skin.
