 Make sure to add this call adapter factory when building your Retrofit instance:
 ```kotlin
 Retrofit.Builder()

     .build()

 There's also an overloaded invoke operator on the NetworkResponse class so that its success body can be accessed directly.
 ```kotlin
-val usersResponse = usersRepo.getUsers().await() // Returns users if response is successful, or null otherwise
-println(usersResponse() ?: "No users were found")
+val usersResponse = usersRepo.getUsers().await() 
+println(usersResponse() ?: "No users were found") // Returns users if response is successful, or null otherwise
