I have a toolbar in activity with a fragment container

    <androidx.appcompat.widget.Toolbar
        android:id="@+id/tlUsersActivity"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@color/white"
        />

I run these lines to control the backpressed button

    setSupportActionBar(binding?.tlUsersActivity)
    if (supportActionBar != null) {
        when (intent.getStringExtra(MainActivityAdmin.FRAGMENT_TYPE)) {
            "View Users" -> {
                supportActionBar?.title = viewUsersText
}

    "Edit Users" -> {
        supportActionBar?.title = editUsersText
    }
}
        supportActionBar?.setDisplayHomeAsUpEnabled(true)
        binding?.tlUsersActivity?.setNavigationOnClickListener { onBackPressed() }

I want to change this action from inside the fragment, I want to replace it with a function that replaces fragments.
I’ve tried this but it didn’t work

    val actionBar = view?.findViewById<Toolbar>(R.id.tlUsersActivity)
    actionBar?.setNavigationOnClickListener {
        replaceFragment(FragmentEditUsers())
    }
