Steps to get vosk-android as an input method on android?

I'm looking for an open source solution to be able to dictate text to other apps on android.
The kõnele project does just that but their app wants to separate the engine to a server that you can configure in the app, so I would need a server setup and running for it I guess? They provide a server for estonian language.

Having tested the demo of vosk-android, I can see it understanding my english well, and it's all happening on my device, which would be the preferred way. The only problem is that how can I get this as an input method to other apps.

The kõnele calls this feature I guess as a speech keyboard that implements the input method editor (IME) API https://developer.android.com/reference/android/inputmethodservice/InputMethodService

If no one has done this yet, what would be the course to take here? Should you fork and code the kõnele project and embed vosk-android there somehow, or would it be easy to just add the IME functionality to vosk-android? I`m very mediocre programmer, so this may be out of my scope, but I'm just curious.
