I have been trying to rotate pdf by 90 degrees (clockwise/anti-clockwise) . i have used method  
“instance.setToolMode(‘rotateCounterClockwiseButton’)” to set tool to my custom button but it didn’t worked.  
i have also tried method from annotManager like below  
“const tool = instance.docViewer.getTool(‘rotateCounterClockwiseButton’);  
instance.docViewer.setToolMode(tool);”  
but this didn’t worked as well !!

so, how can i achieve this rotation of pdf functionality to my custom button?  
can anyone please provide information for the same.

Thank you.
