Sorry but user-based ACLs require the use of Context Directory Agent (CDA - successor to AD agent). There's no option to use locally defined users or other identity sources.
Note CDA isn't really actively maintained by Cisco. The last update was early 2019 when they added Server 2016 support with Patch 6.

That aside, it's pretty simple to setup and use:

Cisco's current strategy is for customers to migrate to using Firepower Threat Defense (FTD) with ISE or ISE-PIC as the identity source.
