I've got an Maatwebsite (v3.1.25) Excel Export as follows. What is the simplest way to add a custom name for each sheet? Currently they just appear as "Worksheet", "Worksheet 1" etc.

I did see the official website's documentation, but couldn't figure out how to apply it to my specific situation.

```
class BizdevReport implements WithMultipleSheets
{

    public function sheets(): array
    {
        $sheets = [
            new BizdevReportTeachers(),
            new BizdevReportClasses(),
            new BizdevReportGMV()
        ];

        return $sheets;
    }

}

```
