Fastlane with Compose - [!] No screenshots were detected 📷❌

Question

Is there a working example of using Jetpack Compose with Fastlane screenshots?

When I try it, I get a "No screenshots were detected" error.

@RunWith(AndroidJUnit4::class)
class ScreenshotTest {

    @get:Rule
    val composeTestRule = createComposeRule()

    @Before
    fun init() {
        Screengrab
            .setDefaultScreenshotStrategy(
                UiAutomatorScreenshotStrategy()
            )
    }

    @Test
    fun useAppContext() {
        Screengrab.screenshot("before");

        composeTestRule.setContent {
            FastlaneTestTheme {
                MainScreen()
            }
        }

        Screengrab.screenshot("after");
    }
}

[12:38:54]: Limiting the test classes run by `screengrab` to just those that generate screenshots can make runs faster.
[12:38:54]: Consider using the :use_tests_in_classes or :use_tests_in_packages option, and organize your tests accordingly.
