Adobe InDesign Version 19.2

Running MacOS Sonoma Version 14.3.1

Apparently there was previously an option in InDesign which auto-saves your documents as you go (with options in Preferences to specify how often you wished the app to auto-save the active document from 1 to 60 minutes). This feature is similar to what Adobe Premiere Pro app has -- even while saving via the "Save As" feature (which overwrites a previous version with the same file name), the auto-save application feature saves the document as you work with it, so that you can go back to previously saved versions to retrieve a version which which predates any lost data, or newly created errors that were saved as overwritten versions to the working document.

My example: I mistakenly "Placed" a PDF document within a page's main text box (instead of Placing it on the following page). It replaced all of the extensive text on that page with this PDF image. Not having realized that (as I was looking at the second page where I also placed the PDF correctly) I "Saved As" the file, which permanently deleted / overwrote all the text I'd spent an hour or more writing and formatting. Thus, there was no Auto-Saved version that predated my error.

It's necessary to re-add this Auto-Save feature to InDesign (as it used to exist) so we can retrieve lost data due to the issue described.
