Is there a way in Jetpack Compose to retreive the real String value of a String Resource for a modifier's contentDescription attribute?

I use Jetpack compose for an android app.I want to retrieve the String value of a String that is already declared in Resources.Strings. I tried everything even context but nothings seems to work. More specifically I want to register a String value from Resources as the contentDescription of composable's modifier so that TalkBack can read this value to the user's system language.The debugger logs an int value instead of a String even when I user .toString() method. Here is the code.

This is the string on values/strings.xml file.

<string name="my_string">Something</string>

This is some of the code for the composable:

....modifier = Modifier
        .fillMaxWidth()
        .focusRequester(focusRequesters[1])
        .clearAndSetSemantics { contentDescription = R.string.mystring.toString() }
)
val test= (R.string.my_string)
Log.d("Test",""+ test )

The debugger shows an integer value to the Android Studio's Logcat. This is output of the Logcat:

D/Test: 2131623845

The expected result should have been:

D/Test: Something

As far as I'm aware, there are currently two ways to do this:

  1. Have the String prepared beforehand, as it is done in Gabriele Mariotti's example, by using the @Composable stringResource function;
  2. Have a Context variable prepared beforehand and then use context.getString():
@Composable
fun SomeFunction() {
   val context = LocalContext.current
   
   TextField(
        label = { Text(stringResource(R.string.some_label)) },
        modifier = Modifier.semantics {
             contentDescription = context.getString(R.string.some_description)
        }
   )
}

Just use the method stringResource:

val test = stringResource(R.string.my_string)

Text("text",
  modifier = Modifier
    .fillMaxWidth()
    .clearAndSetSemantics {contentDescription = test}
)
