add attachments to a feature layer

how to get ArcGis feature from servicefeature table to perform add attachments.

I tried this example and built on it with a different feature layer.
https://github.com/Esri/arcgis-maps-sdk-kotlin-samples/tree/main/edit-feature-attachments

I logged few messages such as the image size, name and if the adding operation is finished but when I check the uploaded attachments there is non. I check the docs as well but didn't find any example or a written code that helped. it lacks in that department

this is what I attempted, check the screen shot the 3rd one after trying to upload a image

private fun addFeatureAttachment(selectedImageUri: Uri) {
    // display a loading dialog
    val dialog = createLoadingDialog("Adding feature attachment").also {
        it.show()
    }

    // create an input stream at the selected URI
    contentResolver.openInputStream(selectedImageUri)?.use { imageInputStream ->
        // get the byte array of the image input stream
        val imageBytes: ByteArray = imageInputStream.readBytes()
        // create the attachment name with the current time
        val attachmentName = "attachment_${System.currentTimeMillis()}.png"
        Log.d("attachment","attachment_${System.currentTimeMillis()}.png")

        lifecycleScope.launch {
            selectedArcGISFeature?.let { arcGISFeature ->
                // add the attachment to the selected feature
                arcGISFeature.addAttachment(
                    name = attachmentName,
                    contentType = "image/png",
                    data = imageBytes
                ).onFailure {
                    return@launch showError(it.message.toString())
                }
                // update the feature changes in the loaded service feature table
                serviceFeatureTable.updateFeature(arcGISFeature).getOrElse {
                    return@launch showError(it.message.toString())
                }
            }
            applyServerEdits(dialog)
        }
    }
}

private suspend fun applyServerEdits(dialog: AlertDialog) {
    // close the bottom sheet, as it will be created
    // after service changes are made
    bottomSheet?.dismiss()

    // apply edits to the server
    val updatedServerResult = serviceFeatureTable.applyEdits()
    updatedServerResult.onSuccess { edits ->
        dialog.dismiss()

        // check that the feature table was successfully updated
        if (edits.isEmpty()) {
            showToast("not")

            return showError(getString(R.string.failure_edit_results))

        }
        // if the edits were made successfully, create the bottom sheet to display new changes.
        selectedArcGISFeature?.let { createBottomSheet(it) }
    }.onFailure {
        showError(it.message.toString())
        dialog.dismiss()
    }
}

fun selectAttachment() {
    val mediaIntent = Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
    activityResultLauncher.launch(mediaIntent)
}

Thank you
