Fail to loggin the simplenote-android app

Currently, I am studying the source code of the simplenote.
I need a new Simperium account to run the app on a device or a simulator.

However, I found that the Registration of Simperium is closed.
I was wondering if you could help me create an account or share the (testing) fields simperiumAppId and simperiumAppKey in the file Simplenote/gradle.properties (I guess you may have simperiumAppId and simperiumAppKey for testing). Otherwise, I cannot debug or study the source code at all.

Many thanks.

### Expected

I need to log in to the app to continually test the app.

### Observed

I build the app in Android Studio and run it in an Emulator (Pixel 6). It works well but I cannot log in to the app.
The reason is that the Registration of Simperium is closed. Hence, I have no simperiumAppId and simperiumAppKey to configure to the app.

### Reproduced

Start with Simplenote/gradle.properties and the Android Studio emulator setup described in the issue. Confirm how simperiumAppId and simperiumAppKey are supplied, then verify that the app can log in; the issue provides no actionable code change because Simperium registration is closed.
