How can I add my own app to the whatsapp audio selection like [this application](https://play.google.com/store/apps/details?id=de.bananadevs.audiosoundrecordershareforwhatsapp) in android (with java)?

I know, I asked [this question](https://stackoverflow.com/questions/52748257/how-can-i-add-an-app-to-the-whatsapp-audio-selection) already but I didn't get a useful answer. I didn't think that it could work, but I found this app and it works on my android phone (Huawei VNC-L31/Huawei P9 Lite, Android 7.0). ([Screenshot](https://i.stack.imgur.com/Wt6bE.png))

I tried it with the one-to-one intent filter from the manifest of this app but it didn't work.

Thanks for grammar correction ;)
