Solution

We can start by installing and opening the app in our emulator

It is a login screen and it says that we need biometrics to login but of course we cannot do that since we are running it in an emulator We must use a biometric bypass Frida script to login For that, I used ` Universal Android Biometric Bypass`
Source: https://codeshare.Frida.re/@ax/universal-android-biometric-bypass/ We can load this script and try to login,

We do see the flag after login, /
