Orderoverview template

I have filtered in my test orders with a new tab. Here i have filtered only my test orders. My test orders are available in shop orders also.
Now I have extended admin order overview controller.

Shop orders i have displayed my test order notes:
‘extend’ => [ \OxidEsales\Eshop\Application\Controller\Admin\OrderOverview::class => \oe\example\Controller\Admin\OrderOverview::class]

New tab for my test orders:
‘controllers’ => [‘exampleordersoverview’ => \oe\example\Controller\Admin\AdminOrderOverview::class]

Above codes I have mentioned in metadata file this is correct or not.

Congratiulations! Do you have a question as well or why is this thead opening?
