Instrumental testing - how to check the view is not existing (JetpackCompose)?

I am using Jetpack compose and there is such an implementation

...
imgRes?.let {
            Spacer(modifier = Modifier.width(4.dp))

            Image(
                painter = it,
                contentDescription = when (metadata.hasSubscription) {
                    true -> stringResource(id = R.string.subscribed)
                    false -> stringResource(id = R.string.not_subscribed)
                    else -> null
                },
                modifier = Modifier
                    .height(17.dp)
                    .width(17.dp)
            )
        }
...

So, when imgRes is not null, I put the view on the screen with dedicated contentDescription according to the hasSubscription state, correspondently in testing, I am checking if the view with specific contentDescription existing on the screen, however, I also need to check the state when imgRes is null and the image is not existing on the screen. But in the case when the view is presented I know how to find it by contentDescription, but how to check if the view is presented if it hasn't any id? How to find this view on the screen?
