Injecting LARAVEL BLADE syntax into NOWDOC

return <<<'HTML'
    <button {{ 
        $attributes->class([
            'px-3 py-2 bg-green-600 text-white rounded-lg',
        ])->merge([
            'type' => 'button',
        ]) 
    }}>
        {{ $slot }}
    </button>
HTML;

This works, but if I change `HTML` to `BLADE` i do not get proper BLADE syntax highlighting. I tried creating a custom language injection and there was no option for LARAVEL BLADE.

Is this possible?
