expected behavior of Enter Passcode when passcodeFallback: true

[tangtai]

so when set passcodeFallback: true, i expect when you press Enter Passcode you should be able to go to the pass code screen and enter your passcode to authenticate yourself with passcode ( as shown in pics). instead i am getting an error of LAErrorUserFallback, so i know it is working in a way. The only case it would promote me to the pass code screen is when i didn't set up touch ID. i really want the option of having authentication with passcode.

the package react-native-passcode-auth is giving me the flow i wanted, while lack at other options.

is there a way to achieve the behavior i wanted using this package?

Is it possible to do this on android?
