On laravel 11 site User model has pivot reference to tasks table

public function uncompletedTasks(): belongsToMany {
    return $this->belongsToMany(Task::class)
        ->using(TaskUser::class)
        ->withPivot('supervisor_id')   // Reference to "task_user" table
        ->where('completed',false)
        ->orderBy('priority', 'desc')
        ->orderBy('deadline_at', 'desc');
    }

and I need having $taskId to check if it exists in read data, something like :

$uncompletedTasks = LoggedUserFacade::getLoggedUser()->uncompletedTasks()->get()->findOrFail($taskId);

as in request above method findOrFail does not exists!

I searched in helpers at https://laravel.com/docs/11.x/helpers, but I did not find any decision…

Sure I know how to check it in foreach block, but maybe some better decision ?

Are there any ?

"laravel/framework": "^11.10.0",

Thanks in advance!
