Cache image for a defined time

[JJSarrasin]

Hello guys,
I'm using coil3 with ktor3.
I have a LazyGrid on Android TV with about 500 TV channels displaying a snapshot of the live TV image. This image is refreshed every 30s..
As the Android TV device are not very powerful, I'd like to put the image in cache for 30s so that when I scroll down/up, it keeps the cache version and navigate smoother than retrigger the image reload as it is in my current scenario above:

    val request = ImageRequest.Builder(context)
        .data(myImageUrl)
        .crossfade(0)
        .memoryCachePolicy(CachePolicy.DISABLED)
        .diskCachePolicy(CachePolicy.DISABLED)
        .build()

    val painter = rememberAsyncImagePainter(
        model = request
    )

    Image(
        modifier = Modifier.fillMaxSize(),
        contentScale = ContentScale.Crop,
        alignment = Alignment.Center,
        painter = painter,
        contentDescription = null
    )

    LaunchedEffect(Unit) {
        while (true) {
            delay(30000L)
            painter.restart()
        }
    }
