Has anyone gotten Cisco NDP discovery working for IPv6?

We have a IPv6 lab up and running and trying to get IPAM (2024.1.0) to scan our 2 Cisco switches (3850 and 9300) using NDP.   The 2 switches are being monitored successfully via SNMP but NDP for IPv6 scanning does not work.  I am not able to connect to the MIB/OID for the following below.   Has anyone successfully got this working in their IPv6 environment?

"IPAM IPv6 address discovery is based on the NDP protocol and information is obtained from routers based on the following MIBs / OIDs:

IPv6 MIB, OID 1.3.6.1.2.1.55.1.12.1.2 (ipv6NetToMediaTablePhysicalAddress)
IP MIB, OID 1.3.6.1.2.1.4.35 (ipNetToPhysicalTable)
ipv6NetToMediaValid - 1.3.6.1.2.1.55.1.12.1.6
Cisco proprietary CISCO-IETF-IP-MIB , OID 1.3.6.1.4.1.9.10.86.1.1.3 (cInetNetToMediaTable)
