Please create a trigger for MS Flow "When a to do tag in OneNote is inserted". I would like to use it to create a Microsoft To Do task. Alternatively, a new tag "Create To Do task" could be introduced in OneNote app. This was part of OneNote 2016 desktop app, which is no longer available.
Also, I ´m very much missing the old "summary of tags used in this section/page/notebook". Using this function, one could have his own to-do list within OneNote.
