Query all tags present in notes under a root folder

[Daamiian]

@dawni

```dataview
TABLE rows.l.text AS "Tags"
FROM "meeting notes"
FLATTEN file.lists AS l
WHERE l.tags
GROUP BY file.name AS "File"

This is the solution, thank you so much. Can I ask, how can I filter this further to just include the files that link to the current doc?
