I want to change the background color of a TextField in Jetpack Compose, but nothing seems to work.

I have tried setting Modifier.background(color = Color.Transparent), but it does not work (color does not change).
Also, I have tried using both colors = TextFieldDefaults.textFieldColors(...) and colors = TextFieldDefaults.colors(...), as suggested in this question, but none of them have backgroundColor or any other parameter related to background (in Material3). I have also tried this approach, but it does not work either.
