Suppose we are creating a collection (array of objects). I am populating a sample row to "Teach" PowerApps which types are in this colleciton. This allows DataTables, for example to connect to that colleciton. You get the idea.
The queston is this: How do I specify types of a property/object explicitly? For example, I want to say that Stakeholder is a field of type User with such and such properties. For example, I want this type to be compatible with the user picker control (combobox).
This is how a proper user type looks like. Note how the Picture looks, for example?
This is a desparate attempt to teach PowerApps that StakeHolder property is a User type:
As you can see I have to idea how to specify types in PowerApps.
Why we need the ability to specify types:
1) to avoid the annoying error saying that the types are incompatible
