Review comment:
Right. So group_topics is the collection we are unnesting and inside
this collection I don't think there is another collection. So if we put some
dummy data to create another array inside group_topics, then we can add the
following unnest config to the test
```
"complexTypeConfig": {
"unnestFields": [
"group.group_topics",
"group.group_topics.inner_array"
]
}
```
I don't think unnesting collection inside another collection is covered in
other tests.
