Yubikey Cryptsetup Unlock Does not work

On L5 turn on you have to enter a crypt passcode for encrypted phone memory partition.

I am using a USB-C yubikey with static password slot . On inserting the key it does for some reason not populate the static passcode in the field and only ~8 or so digits are populated. My passcode is more like 20.

The L5 should detect the yubikey simply as an external USB keyboard and pass those key presses into the text entry field.

How could i configure the L5 cryptsetup/bootloader to detect usb devices correctly at launch?

PS: once PureOS is booted up they yubikey works as intended and passphrase is passed correctly through usb-c
