Change an AsyncImage into a bitmap

Question

I'm currently using jetpack compose to code a pokemon GO like game. I have my markers on my map and I use AsyncImages to get images from the PokeAPI. The problem is I need to give bitmaps to my markers but I don't know how to do. I'd appreciate any help.

I tried to change the Async image as you can see in the screenshot but it's not working like this.

Full code :

    class MainActivity : ComponentActivity(){
        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)

        setContent {
            val height = 200
            val width = 100
            val loader = ImageLoader(this)
            val bitmapdraw = BitmapFactory.decodeResource(applicationContext.resources, R.drawable.charac)
            val smallMarker = Bitmap.createScaledBitmap(bitmapdraw, width, height, false)
            val location = LatLng(47.394144, 0.68484)
            Column() {

                MapScreen(location)

                Row(
                    modifier = Modifier
                        .fillMaxWidth()
                        .height(50.dp)
                        .background(Color.Green.copy(alpha = 0.1f))
                        .weight(1f, true),
                    horizontalArrangement = Arrangement.SpaceAround,
