Are there specific properties required for modules to interact effectively?

For modules in OutSystems to interact effectively, they do need to be designated as Public. This is crucial because Public properties enable access to the elements contained within a module from other modules. By declaring an element as Public, you ensure that it can be reused and referenced throughout different modules, fostering modular design and code reusability, which are essential principles in software development.

If elements are not marked as Public, they are considered Private, restricting access solely to within that module. This restrictiveness would hinder the interaction between modules, limiting functionality and integration. Thus, having Public properties is necessary for facilitating clear and effective communication between different parts of an application.
