Went to the JAMF link provided:
https://jamfnation.jamfsoftware.com/viewProduct.html?id=41&view=info
Downloaded the installer:
Download: https://admdownload.adobe.com/bin/live/AdobeFlashPlayer_18_a_install.dmg
Open the .DMG and then right click and show package contents of the 'Install Adobe Flash Player'. Navigate to ContentsResources. However i do not see any type of installer .PKG in this location as other discussions here have pointed out with prior versions. Is the file no longer present? Is there a new way to install Flash that does not utilize this? Any way to get that .PKG from another source?
