Tried the 'Create Mindmap' function in NotebookLM : Lacklustre

 Tried the 'Create Mindmap' function in NotebookLM just now. 

I uploaded a WORD file which is the rundown of a class session. This rundown contains the main topics and the subtopics to be covered. 

Then I asked NotebookLM to turn it into a mindmap. The output was an interactive (collapsible and expandable) mindmap. 

But, this interactive mindmap can't be shared via a link. If downloaded, it becomes a static PNG image. 

In that case, I should continue to use EdrawMind. 

Or, maybe NotebookLM should be used to generate mindmaps from uploaded source materials.
