Navigation View Android Kotlin with Espresso - androidx.test.espresso.NoMatchingViewException

Question

I am new to Espresso trying to write testcase of NavigationView menu item click.

Below method in HomeActivityClass

accountMenu is the NavigationView predefined class, actionView is the View predefined class

private fun updateNavigationItems() {
        with(binding.accountMenu.menu) {
           
        findItem(R.id.nav_account_legal).actionView?.findViewById<TextView>(R.id.item_title)?.text =
                getString(R.string.legal)
         }
    }

Below is the test class which I have implemented

@ExperimentalTextApi
@RunWith(AndroidJUnit4::class)
class HomeActivityTest2 {

    @get : Rule
    var myActivtyRule = ActivityScenarioRule(HomeActivity::class.java)
    
    @Test
    fun legal(){
        onView(withText("Legal")).perform(click())
    }
}

when I try to run legal method I am getting below exception

androidx.test.espresso.NoMatchingViewException: No views in hierarchy found matching: an instance of android.widget.TextView and view.getText() with or without transformation to match: is "Legal"

View Hierarchy:

Could you please help me on this. I am stuck at this. Thanks in advance.
