Local Management Admin accounts are not visible in Jamf Pro computer inventory records under Inventory > General > Managed Local Administrator Accounts or Inventory > Local User Accounts > Managed Local Administrator Accounts.

Confirm that the Jamf Pro user account that is being used is configured with the Jamf Pro Server Actions privileges to View Local Admin Password. Without that privilege nothing will show up for the Managed Local Administrator Accounts.

This is especially common for Jamf Pro user accounts configured with "Custom" privileges, as the "View Local Admin Password" was a new privilege added in 10.46 along with the introduction of LAPS (https://learn.jamf.com/en-US/bundle/jamf-pro-release-notes-10.46.0/page/New_Features_and_Enhancements.html) and would not have been automatically enabled for accounts with custom privileges.
