In case someone needs an automatically generated hubnote/MOC/TOC, we can use dataview table or list. I know, it doesn’t really show the “links”, but if the dataview block is placed inside an Admonition (ad-note etc), all the listed files are shown as links in graph view 
It doesn’t really show anywhere else (backlinks or outgoing links).
I had seen a post somewhere about a button which copies a query into the text. Can be a quick fix too 
Since all my posts are aligned in cascading tags (#note/knowledge/exam1/paper1/subject), dataview tables is a lot easier. Plus the manual linking is in place wherever necessary.
