Did you also imported the deeplink module and set that up. Because you need a deeplink called ForgotPassword. Check the documentation again on how to configure the deeplink.
Did you call the StartDeeplink microflow after startup? Go to Project -> Settings -> Model then click on show. This will display the after startup microflow. I believe you need to call the StartDeeplink microflow here. If the microflow doesn't exist, create one.
You will also need to call the DeepLinkHome microflow before directing your users to the home page. This microflow returns a boolean. If it's false, show the default Home Page else just go to and end activity.
Refer to the Deep Link Module documentation in the App Store for more information.
Make sure you call MF "Nav_GuestHomePage" to open home page from navigation.Make sure you call MF "Nav_GuestHomePage" to open home page from navigation.
