we do some changes on our SharePoint Online Search Schema and the Managed Properties. Now I need a list of WebPages that uses the "old Managed Property" in a Highlighted Content Web Part so I can update those to the new property name.
I thought it must be something like "a Content Search restricted to the Filetype Site Page" but I didn't found any helpful information how to tackle this.
Yeah, I have solved it! The page content is stored in the site page property CanvasContent1. I have written a script that checks if the name of the old managed property is contained in it, that works for me,
