Finding List names for hidden SP site lists

[williams500]

I am trying to create a flow revolved around the comments of a page. Comments are stored as a list in the background but, obviously, that list is not selectable by default in Flow. I am mainly stuck on how to find the list name to set that as a parameter in the flow. Does anyone know where or how to check this?

I would think that typing the name of the list in as a custom value (assuming you know the name of the list you need), that should work; Flow doesn't seem to list every list in its dropdowns, but it does work the "hidden" ones you speak of, like Calendars.

To find the List name of Hidden SharePoint List, try opening the Site in SharePoint Designer 2013.  You will be able to see all the hidden List.  Including the Comment.Guid List.  U Can un Hide it from there. 

To your actual problems, modern Page comments are not stored in the Hidden List.  They are now moved to a different datastore but accessible via rest api. Check this link https://www.vrdmn.com/2017/07/working-with-page-comments-rest-api-in.html

Thanks for the response. I suppose that would make it difficult to use the Microsoft Graph API through Microsoft Flows triggered by comments, seeing as how that would rely on comments being stored as a list that can be monitored? I have been going with the basic concept of:

I am essentially trying to notify a list of 'Followers' whenever a new comment is made on a particular site page.
