Viewer Document Rotate buttons at top bar

Hello,

I want to rotate files that I display in viewer.
I see some example screenshots at groupdocs home page but when I try online live demo groupdocs I couldnt see rotate buttons at top. And When I look at the config option at startup I can see there is “HidePageRotationControl()” but even I didint use this still rotate buttons not showing at top bar.

Im using .Net Core groupdocs viewer project. Also in attachment files.

How could I achieve this? I attached the necessary screenshot about situation
Thank you.

Rotation is not supported at the moment. We have planned to add this feature next month. The issue ID for reference is VIEWERNET-4368. We’ll let you know when it will be implemented.
