Sorry maybe this is such a dummy question.
I want to try managing term store in sharepoint online. I got this tutorial in Office Support to create new group in term store
It said that to create new group I should right-click or point to taxonomy header and there will be an arrow and option to create New Group. But I can't find it in my sharepoint online. I already tried to point my cursor into taxonomy header or also right click the taxonomy header, but there is no option to create new group.
