How do I start file chooser using intent in compose

I am trying to start file chooser on a button click (composable function). Unable to use startActivityForResult().

@Composable
fun SelectScreen() {

    Button(onClick = {
        val intent = Intent(Intent.ACTION_GET_CONTENT)
        startActivity(intent)
    }
    ) {
        Text("BUTTON")
    }
}

Here is my suggestion:

val pickPictureLauncher = rememberLauncherForActivityResult(
    ActivityResultContracts.GetContent()
) { imageUri ->
    if (imageUri != null) {
        // Update the state with the Uri
    }
}

// In your button's click
pickPictureLauncher.launch("image/*")

and in your composable which display the image, you can do the following

val image = remember {
   // Make sure to resize and compress
   // the image to avoid display a big bitmap
   ImageUtils.imageFromUri(imageUi)
}
Image(
   image,
   contentDescription = null
)
