How to unit test if an image was loaded using Coil + Compose

I'm loading an image using Coil for Compose like below.

@Composable
fun SvgImageSample() {
    val painter = rememberAsyncImagePainter(
        model = ImageRequest.Builder(LocalContext.current)
            .decoderFactory(SvgDecoder.Factory())
            .data("https://someserver.com/SVG_image.svg")
            .size(Size.ORIGINAL)
            .build()
    )
    Image(
        painter = painter,
        modifier = Modifier.size(100.dp).testTag("myImg"),
        contentDescription = null
    )
}

The image is loaded properly. Now, I would like to write a test to check if the image was loaded. Is there any assertion out-of-the-box for that?

Something like this:

class MyTest {
    @get:Rule
    val composeTestRule = createComposeRule()

    @Test
    fun checkIfTheImageLoads() {
        composeTestRule.setContent {
            MyAppThemeTheme {
                SvgImageSample()
            }
        }
        composeTestRule.onNodeWithTag("myImg")
            .assertCoilImageIsLoaded() // <- this is what I want
    }
}
