Unable to zoom mind map when research in open in a Mac window while mind map is being used in iPad side car

So my workflow is like this :

  1. I have separate windows open of the same study in Mac and Ipad using sidecar
  2. I use research in full screen in the mac window while my documents and mindmap are open in the window of the iPad
  3. Whenever I open research window, I am not able to zoom in or out of the mindmap in the iPad window alone . all other options are doable, like pan etc. but not able to zoom alone
  4. but i am still able to zoom in the mac window

Kindly help me out with this as my workflow requires me to use research extensively in one screen while i edit and make mindmaps in the other
