I can't point you to any Apple materials as we discovered this once we 
notarized out DMG for Catalina and was performing final installation 
testing on Catalina and other versions of macOS

You can download the macOS DMG for our app at 
http://www.researchware.com/downloads.html

Scroll down the page to the download links. You will see ONE DMG for 
Catalina and another DNG for other version of OSX. Download the Catalina 
DMG and you will find the notarized DMG opens on Catalina, Mojave, and 
High Sierra, but throws and error on Sierra and below.

We choose to Notarize the DMG rather than the installer app. I realize 
while Apple allows this (currently) is is not what their documentation 
on Notarization speaks to which is Notarizing the APP and performing 
drag-installs from the DMG rather than using an Installer app.

Our application HyperRESEARCH, our Installer are both code signed. The 
Catalina DMG is code signed, notarized, and stapled. The non-Catalina 
DMG is not code signed (and not notarized).

We used this excellent guidance to figure out how to do notarization:
