I have been using krypted's MakeMeAnAdmin script. It works great for elevating standard users to admin users and demoting them back to standard users. I cannot get the script to generate a log. Does anyone have an updated fully functioning version of this script available?
Question
MakeMeAnAdmin Update? Log fix?

+15What kind of logging are you looking for? The script I'll put below is a modification I made to the script you mentioned, but it creates a log file, writes the user who is being elevated, the time they are elevated, and writes how many times they've elevated. You can change my "$CUSTOM" to your org. I don't know a good way to log what actions are taken with admin privlages though.

I'm not sure it would be feasibly possibly to make a log of the actions taken while a user has escalated permissions. Everything would be recorded in Unified Logging, but Apple does not exactly make that easy to parse or export. Jamf Protect would redirect the logs to SIEM, but then filtering the logs for meaningful data is another chore. Just furthers your point of no easy way to gather what a user did with the permissions.
