I don't know enough to help you, but I can tell you that your best source for prior art on dadb is to look at the Maestro source code :)

I have solved the problem:

The issue here is creating and reading the AdbKey.

The AdbKeyPair.readDefault() code executes on the PC directory :

    @JvmStatic
    fun readDefault(): AdbKeyPair {
        val privateKeyFile = File(System.getProperty("user.home"), ".android/adbkey")
        val publicKeyFile = File(System.getProperty("user.home"), ".android/adbkey.pub")

        if (!privateKeyFile.exists()) {
            generate(privateKeyFile, publicKeyFile)
        }

        return read(privateKeyFile, publicKeyFile)
    }

But my device is a phone or a TV, so I added the following code:

    @JvmStatic
    fun readAndroidDevices(file: File): AdbKeyPair {
        val privateKeyFile = File(file, "adbkey")
        val publicKeyFile = File(file, "adbkey.pub")

        if (!privateKeyFile.exists()) {
            generate(privateKeyFile, publicKeyFile)
        }

        return read(privateKeyFile, publicKeyFile)
    }

And here's how I used it to make it work:

override  fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main2)
    
    Executors.newSingleThreadExecutor().execute {
        Dadb.create("localhost",5555, AdbKeyPair.readAndroidDevices(filesDir)).use {  dadb ->
            dadb?.shell("getprop ro.product.model")?.output?.trim()
        }
    }
}
