Creating Laravel Blade Language Injection Follow

I want to create Laravel Blade language injection for inside of a NOWDOC

e.g.:

public function render()
{
    return <<<'blade'
        <div>
            navbar
        </div>

        <div class="container">
            {{ $slot }}
        </div>
    blade;
}

There is no option for "Blade" or "Laravel Blade" in the language ID options.

How do I do this?
