Show Sidebar on a Addon Module Page

[hosttech]

Hey folks

I'm trying to display a sidebar on a custom addon module page. It seems like the template used does not even support a sidebar on that page. But I cannot figure out what's wrong with it.

Basically, I'm extending domain functionality. So I'd like to display the Domain sidebar.

I've done this:

URL for custom page: 

index.php?m=MODULENAME

My Hook:

add_hook('ClientAreaPrimarySidebar', 1, function ($menu) {

    if(!empty($_GET['domainid'])){
        $domainid = $_GET['domainid'];
    }else{
        $domainid = $_GET['id'];
    }

    if ($_REQUEST['m'] === 'MODULENAME'){

        $clientid = $_SESSION['uid'];

        $client = Client::find($clientid);

        $domain = Domain::where('id', $domainid)->get()->first();

        Menu::addContext('client', $client);
        Menu::addContext('domain', $domain);
        $menu = Menu::primarySidebar('domainView');
    }
});

var_dump'ing the $menu even gives the correct structure. So the Sidebar is perfectly fine. But it is not rendered. What am I missing?

 

Thank you in advance!
