[1.3.0] No Bluetooth in Monterey installer on MacPro 5,1

I created a bootable USB drive using the GUI app, the build logs correctly show the Legacy Bluetooth support kext, however once I get to the Monterey installer, I get stuck trying to connect my Apple Wireless Keyboard (MC184D/B).

They keyboard does however work in Mojave as well as in the bootpicker, I’m even able to do NVRAM resets but the Monterey installer doesn’t seem to recognize it.

Did I do something wrong?
