I created a massive org chart, pretty much horizontal... Which makes it very hard to see the overview. Therefore some parts of my chart i would like to change from horizontal to vertical.

I see there are vertical templates (Vertical Org Chart is one of them), I also see in one of the questions here that it’s possible to click on an icon to change the orientation, but in my chart that icon is not visible...
 

any help would be appreciated :)

thank you
