Problem with BasicTextField in Jetpack Compose on Wear OS

Question

I'm new in Compose and I'm having a problem with input text field on Wear OS. The problem is that I can't get soft keyboard to work as it usually does on Android. Also, when I tried to implement the same layout in XML - it worked. So, when I tap on input text field the keyboard pops up and then hides. When I tap again - keyboard pops up and stays open, but if I try to enter any text - nothing appears in the input field (on the keyboard itself), although entered text is passing down to input text field on UI.

Here is what I get in logs on emulator when I tap on input text field to open the keyboard:

2021-11-24 09:44:36.569 W/IInputConnectionWrapper: getTextBeforeCursor on inactive InputConnection
2021-11-24 09:44:36.571 W/IInputConnectionWrapper: getTextAfterCursor on inactive InputConnection
2021-11-24 09:44:36.649 W/RecordingIC: requestCursorUpdates is not supported

Here is what I get on real device:

And here is my 'composable':

@OptIn(ExperimentalComposeUiApi::class)
@Composable
fun ActivationScreen() {

    var key by remember { mutableStateOf("") }

    var isReady by remember {
        mutableStateOf(false)
    }

    Column(modifier = Modifier
        .padding(40.dp)
        .fillMaxSize()
    ) {
        val keyboardController = LocalSoftwareKeyboardController.current
        val focusRequester = FocusRequester()
        BasicTextField(
            value = key,
            onValueChange = {
                //isReady = it.length>11
                key = it
            },
            singleLine = true,
            keyboardOptions = KeyboardOptions.Default.copy(
                imeAction = ImeAction.Done
            ),
            keyboardActions = KeyboardActions(
                onDone = {
                    keyboardController?.hide()
                }
            ),
            modifier = Modifier
                .size(140.dp, 20.dp)
                .background(Color.White)
                .align(Alignment.CenterHorizontally)
                //.focusRequester(focusRequester)
                //.focusOrder(focusRequester)
        )

        Text(
            text = "ACTIVATION",
        )

        val status = if (isReady) "READY" else "NOT READY"
        Text(
            text = status,
        )
    }
}

Based on @Yuri Schimke's answer, here's a generic component implementation that accepts placeholder, value and onChange as attributes.

import android.app.RemoteInput
import android.content.Intent
import android.os.Bundle
import android.view.inputmethod.EditorInfo
import androidx.activity.compose.rememberLauncherForActivityResult
import androidx.activity.result.contract.ActivityResultContracts
import androidx.compose.foundation.layout.*
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp
import androidx.wear.compose.material.Chip
import androidx.wear.compose.material.Text
import androidx.wear.input.RemoteInputIntentHelper
import androidx.wear.input.wearableExtender

@Composable
fun TextInput(
  placeholder: String,
  value: String?,
  onChange: (value: String) -> Unit,
) {
  val launcher =
    rememberLauncherForActivityResult(ActivityResultContracts.StartActivityForResult()) {
      it.data?.let { data ->
        val results: Bundle = RemoteInput.getResultsFromIntent(data)
        val newValue: CharSequence? = results.getCharSequence(placeholder)
        onChange(newValue as String)
      }
    }
  Column() {
    Chip(
      label = { Text(if (value == null || value.isEmpty()) placeholder else value) },
      onClick = {
        val intent: Intent = RemoteInputIntentHelper.createActionRemoteInputIntent();
        val remoteInputs: List<RemoteInput> = listOf(
          RemoteInput.Builder(placeholder)
            .setLabel(placeholder)
            .wearableExtender {
              setEmojisAllowed(false)
              setInputActionType(EditorInfo.IME_ACTION_DONE)
            }.build()
        )

        RemoteInputIntentHelper.putRemoteInputsExtra(intent, remoteInputs)

        launcher.launch(intent)
      }
    )
  }
}

Attention: this requires androidx.wear:wear-input:1.2.0+
