how to change the locale in the middle of an compose ui test. I tried with the below approach. But it doesn't work

`fun setLocale(locale: Locale) {`
     `val resources = InstrumentationRegistry.getInstrumentation().targetContext.resources` 
     `val config = resources.configuration config.setLocale(locale)` 
     `resources.updateConfiguration(config, resources.displayMetrics)` 
`}`

and the test is

`@Test`
`fun  testChangeLocaleInMiddle() {`
    `composeTestRule.onNodeWithText("Hello").assertExists()`
    `// Change the locale to Tamil`
     `setLocale(Locale("ta"))`
    `// Recompose the UI`
    `composeTestRule.activityRule.scenario.onActivity { activity ->`
          `activity.recreate()` 
    `}` 
    `// Allow time for the activity to recreate` 
    `Thread.sleep(1000)` 
    
    `// Perform actions in the new locale` 
    `composeTestRule.onNodeWithText("வணக்கம்").assertExists()` 
`}`

Use `DeviceConfigurationOverride` API, specifically `Locales` fun <https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/ui/ui-test/src/androidMain/kotlin/androidx/compose/ui/test/DeviceConfigurationOverride.android.kt;l=111?q=DeviceConfigurationOverride&amp;ss=androidx%2Fplatform%2Fframeworks%2Fsupport:compose%2F|https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]ride&amp;ss=androidx%2Fplatform%2Fframeworks%2Fsupport:compose%2F> if you're on Compose 1.7.
you can see this API in action in <https://github.com/android/nowinandroid/blob/420076f01aadd61f650b6848cd23643ca59226b8/app/src/testDemo/kotlin/com/google/samples/apps/nowinandroid/ui/SnackbarInsetsScreenshotTests.kt#L50|Now in android>
Or use <https://google.github.io/accompanist/testharness/|Accompanist testharness> in earlier compose versions
