Hello everyone,

has anyone used react-native-incall-manager in new version of react-native?

Native modules (for example: MainApplication.kt) for android in the new version of react-native is in Kotlin. so, i tried instructions in the documentation of react-native-incall-manager by converting to Kotlin, but i did not work. Anyone has a solution for that? it could be also without using react-native-incall-manager

We use `InCallManager.setSpeakerphoneOn(true);` which works for us, didn’t notice it breaking at least…

We have these versions in our managed Expo project, if they help.

```auto
        "react-native": "0.73.4",
        "react-native-incall-manager": "^4.0.1",
        "expo": "^50.0.11",

```

`npx expo prebuild` generates `MainApplication.kt`, so I suppose yes. I even tested that the speaker still works.
