Passwordless Flow in React Native / Expo

Hello, everyone.
I am now trying to integrate passwordless user auth flow in React Native / Expo application.
I setup everything in auth0 dashboard (Custom SMTP email providers, Email Connections in passwordless, configured in applications)
And I installed react-native-auth0 sdk in my expo application and configured domain and customScheme using expo config mod.
After building the app when I am using authorize method from useAuth0 hook, I can see a new popup coming for user login with email & password.
What I want to do is implement OTP flow, so I tried to call sendEmailCode method from useAuth0 hook, but nothing happens.
Can someone help me what I am missing here?

Plus, this happens when I try initiate passwordless flow in auth0 dashboard.
