Topic on Skin talk:Minerva Neue

Is it possible to add a Log In link into the side menu? I tried using the Skin:Minerva_Neue/Hooks/MobileMenu but wasn't having any luck.

I am not using Extension:MobileFrontend if that makes any difference. And I do not wish to install it either.

Indeed it is done through this hook. Here is the code that does it on Wikimedica:

$wgHooks['MobileMenu'][] = function ( $name, \MediaWiki\Minerva\Menu\Group &$group ) 
{
	if ( $name == 'discovery' ) 
	{
		$group = new \MediaWiki\Minerva\Menu\Group( 'p-navigation' );

		$group->insertEntry( new \MediaWiki\Minerva\Menu\Entries\HomeMenuEntry(
			'home',
			wfMessage('mobile-frontend-home-button')->text(),
			\Title::makeTitle(NS_MAIN, 'Accueil')->getLocalUrl()
		) );
		$group->insert( 'À propos' )->addComponent(
			'À propos',
			\Title::makeTitle(NS_PROJECT, 'À_propos')->getLocalUrl(),
			//MobileUI::iconClass( 'mf-upload-invert', 'before' ), 
		);

		$group->insert( 'FAQ' )->addComponent(
			'FAQ',
			\Title::makeTitle(NS_PROJECT, 'FAQ')->getLocalUrl(),
			//MobileUI::iconClass( 'mf-upload-invert', 'before' ), 
		);

		$group->insert( 'Gestion' )->addComponent(
			'Gestion',
			\Title::makeTitle(NS_PROJECT, 'Accueil')->getLocalUrl(),
			//MobileUI::iconClass( 'mf-upload-invert', 'before' ), 
		);
	}
	else if($name == 'sitetools')
	{
		$group->insert( 'Contribuer' )->addComponent(
			'Contribuer',
			\Title::makeTitle(NS_PROJECT, 'Contribuer')->getLocalUrl(),
			//MobileUI::iconClass( 'check', 'before' ), 
		);

		$group->insert( 'Aide' )->addComponent(
			'Aide',
			\Title::makeTitle(NS_HELP, 'Accueil')->getLocalUrl(),
			//MobileUI::iconClass( 'help', 'before' ),
		);

		$group->insert( 'Poser une question' )->addComponent(
			'Poser une question',
			\Title::makeTitle(NS_HELP, 'Forum')->getLocalUrl(),
			//MinervaUI::iconClass( 'speechBubbles', 'before' ), 
		);
	}
	else if($name == 'sitelinks') 
	{ 
		$group = new \MediaWiki\Minerva\Menu\Group( 'sitelinks'); 

		$group->insert( 'Conditions d\'utilisation' )->addComponent(
			'Conditions d\'utilisation',
			\Title::makeTitle(NS_PROJECT, 'Conditions d\'utilisation')->getLocalUrl()
		);
	}
};

I could not get the icons to work though.
