No option to use Touch ID on Magic Keyboard while Mac is in clamshell mode

Update: I noticed that even Mac OS's native lock/login screen was not giving me the option to use Touch ID whenever the lid was closed. This made me think it's not a 1Password issue. I was able to fix the problem (both on the Mac OS login screen and the 1Password unlock screen) by connecting my Magic Keyboard to my laptop via lightening cable, turning the Magic keyboard off and then on, and then disconnecting the cable. I have no idea why that worked.
