How can I pass data from view or controller to view composer

Hi,

I have the following view composer

public function boot()
{
	view()->composer(['suggested-activities'], '\App\Http\Composers\Frontend\Activities\SuggestedActivitiesComposer@compose');
}

class SuggestedActivitiesComposer
{

    public function compose(View $view)
    {
            $view->with('activities', $this->doSomeAwesomeStuff($view->getData()['MYVARIABLE']) );
    }


	public function doSomeAwesomeStuff($somevar)
	{
		...
	}

}

How can I get MYVARIABLE variable from the controller? OR from the view? In my view I tried to add in my view

@include('suggested-activities', ['MYVARIABLE' => $content->id])

but that does not work ...

I don't mind getting the value from the controller if that's easier but it feels more logical to me to get the value from the view
