Mac agent access to Keys

We use a Mac as a Jenkins agent to build the installer for our Mac application. The script compiles things, signs, builds a dmg, has it notarized, etc… This all works - EXCEPT that I have to manually respond to 8 or so prompts for an Admin ID and password so the script can access the keys.
This is NOT usable for an automated build. I’ve done searches and found several possible solutions - all of which either reference Dialogs that don’t seem to exist, or just don’t work.
One of the complications here is that the “Jenkins” user is NOT an administrator. The Mac mini is currently running Mac OS 13.2.1. Anyone know how to pre-authorize the key access so this process can run unattended?
