Laravel Excel - Catch exception in queued export with chain

Context: I have an export that I want to mail to its intended recipients once it is stored.

I do this inside a Job class.

public function handle(): void
{
    (new ReportExport($this->report, $this->date))->queue($this->report->path)
        ->chain([
            new NotifyReportRecipients($this->report),
        ]);
}

Inside the export, I'm using the FromGenerator concern.

public function generator(): Generator
{
    $query = DB::query()->select(...)->from(...)->where(...);

    return $query->cursor()->getIterator();
}

This already works.

Now, I want to send a different notification but only in the case the export is empty, so I'm trying to cause an exception so I can handle it in the Job class.

use Path\To\MyException;

public function generator(): Generator
{
    $query = DB::query()->select(...)->from(...)->where(...);

    throw_if($query->count() === 0, MyException::class);

    return $query->cursor()->getIterator();
}

But it does not work since the Laravel-excel developers didn't implement a catch method for their QueuedExport class.

public function handle(): void
{
    (new ReportExport($this->report, $this->date))->queue($this->report->path)
        ->chain([
            new NotifyReportRecipients($this->report),
        ])
        ->catch(function (MyException $e) {
            new NotifyReportRecipientsAboutEmptyReport($this->report),
        });
        //  Error  Call to undefined method Maatwebsite\Excel\Jobs\QueueExport::catch()
}

I've tried using a try...catch block

public function handle(): void
{
    try {
        (new ReportExport($this->report, $this->date))->queue($this->report->path)
            ->chain([
                new NotifyReportRecipients($this->report),
            ]);
    } catch (MyException $e) {
        NotifyReportRecipientsAboutEmptyReport::dispatch($this->report);
    }
}

But it does not work.

I've tried following the documentation for Laravel excel and just add a failed method to my Export class but this doesn't work either.

use Path\To\MyException;

public function failed(Throwable $e)
{
    if ($e instanceof MyException) {
        NotifyReportRecipientsAboutEmptyReport::dispatch($this->report);
    }
}

public function generator(): Generator
{
    $query = DB::query()->select(...)->from(...)->where(...);

    throw_if($query->count() === 0, MyException::class);

    return $query->cursor()->getIterator();
}

What's worse, is that the chain just dispatches the Notification regardless.

Does anyone know the correct way to deal with this?
