Get total of imported records with laravel excel

I import records using the Laravel/Excel library. Everything works fine but I would like to get the total number of records imported when the action is performed.

How can I get this data?

I currently have the following code:

Import class where I define the variable $numrows that is increased for each iteration in the import process and I create a getter method to obtain the data stored in it from the controller.

private $numrows = 0;

public function collection(Collection $rows)
{
    $cod_cliente = auth()->user()->client->id;

    foreach ($rows as $row) 
    {

        $this->$numrows++;

        /*Asignación de Cód Employee */
        $cod_employee = 'CNT-' . $cod_cliente . '-' . $row['cod_employee'];
       
        $sex = ucfirst($row['sex']);

        Employee::create(
            [
                'cod_employee'      => $cod_employee,
                'sex'               => $sex,
                'age'               => $row['age'],
                'birth_date'        => $row['birth_date'],
                'educational_level' => $row['educational_level'],
                'num_children'      => $row['num_children'],
                'client_id'         => $cod_cliente
            ]
        );
    }
}

public function getRowCount(): int
{
    return $this->numrows;
}

Controller that validates the existence of a file to import and obtains the number of imported records. But here it tells me that the variable $numrows is not defined.

public function importEmployees(Request $request)
{
    $validatedData = $request->validate(
        [
            'file' => 'required',
        ]
    );
    
    try {
        $import = new EmployeesImport();
        Excel::import($import, request()->file('file'));

        $totalreg = $import->getRowCount();

        Log::info(
            "¡¡Importación de registros!!. La importación de empleados se ha completado." 
        );

        return redirect()->back()->with(
            'success', 'Datos importados correctamente.'
        );
    } catch (\Throwable $th) {
        Log::error(
            "¡¡ERROR!!. Proceso de importación no completado. Error: "
            . $th->getMessage()
        );

        return redirect()->route('admin.employees.index')->with(
            'error', 'Error de importación. Contacte con el administador del sistema. '
            . $th->getMessage()
        );
    }   
}

All the best.
