How to test toast with espresso in DialogFragment - Android

Question

I am trying to test showing Toast but it shown while DialogFragment open (not Activity). I have checked THIS post but most of answers are old / deprecated / for Java. What is the correct way to test it?

My code

@Test
fun testingToast() = runBlocking {
    launchFragmentInHiltContainer<EditModeDialog> {
            onView(withText(R.string.error_message))
                .inRoot(withDecorView(not(activity?.window?.decorView))).check(matches(isDisplayed()))
       }
}
