Accessing sample data in Arcade Playground

Question

@XanderBakker -  in an early post regarding attribute rules  you mention:

Using the playground is great to check functions and logic, but you won't have access to your data and the sample data provided is very limited (2 polygon layers).

How does one access the sample data to test an attribute rule's logic?

Switch the Profile, and the layers / functions available will update accordingly.

Attribute Rule Calculation, for instance, has two layers in the $datastore object.
