How to create and set a variable in azure data factory v2

Question

How do I set an variable of type array of strings in ADF v2 so that I can iterate over each element? Each element represents a database name?

The 'Set Variable' activity has a dropdown but displays 'no results found'?

Many thanks,

from the official doc:

Use the Set Variable activity to set the value of an existing variable of type String, Bool, or Array defined in a Data Factory pipeline.

You'll need to use the pipelines Variable first:
