CG3000D-RG & C6220 AC1200; Programmatically Read Assigned IP & MAC Addresses

How do I programmatically read the assigned IP address with their MAC from the router.

I know I can use a web browser and manually see the assigned IP addresses in the router, but need to programmatically read the addresses because Windows 11 does not update it's arp when the router assigns an IP address when a device attaches to my network. I know I can make Windows 11 arp update by ping IP address, but do not know the IP address for the device with out reading it from the router.

Any suggestions would be appreciated.
