How do I access the parent fragment's children views from a ViewPager?

Question

I have the following XML layout and inside my ViewPager there is a fragment that I am in. From within that fragment how do I access the MaterialToolBar?

<DrawerLayout
    <CoordinatorLayout
        <ViewPager
        <MaterialToolBar
        

Answer 1

I figured it out after an hour, you have to repeatedly keep finding the parent fragment until you hit the correct one....

In my case I had to do parentFragment?.parentFragment?.parentFragment?.my_toolbar?

Is that supposed to be a great grandparents or something ...
