Question: How do I find references of `default` in `export default <CallExpression>`?

```TypeScript
import Axios from "axios"

export default Axios.create({
baseURL: "",
headers: { "Content-Type": "application/json" },
})
```

The issue names no repository file, test, or entry point, and only provides a TypeScript example using export default with a CallExpression. Start by locating ts-morph's AST navigation for this construct; done would require a documented, reproducible way to find the default export reference.
