Intel NUC iwm0 (Intel Dual Band Wireless AC 8260) supported?

I recently obtained an Intel NUC and, of course, installed FreeBSD on it.  Everything that I need works except for the built-in wireless.  Though it shows at boot (as iwm0), after booting, it doesn't show up as a network interface.  I tried installing the iwmbt-firmware-20221109 port and using it, but it didn't help (successfully applied, but no change).  Is there something I am missing or is this particular device not supported?

# iwmbtfw -I -d ugen0.3 -f /usr/local/share/iwmbt-firmware
iwmbt_is_8260: found 8260/8265
main: Firmware has already been downloaded
main: Firmware download is successful!

pciconf sees:

# pciconf -l | grep iwm
iwm0@pci0:1:0:0:	class=0x028000 rev=0x3a hdr=0x00 vendor=0x8086 device=0x24f3 subvendor=0x8086 subdevice=0x9010

    vendor     = 'Intel Corporation'
    device     = 'Wireless 8260'
    class      = network

Kernel modules are autoloaded for it:
