1. Create a blank canvas to list results
2. On the screen, create a "DataAction" and in the flow call the "GetUniversityByCountry" serveraction.
3. In the country parameter, simply enter the desired country.
4. After the serveraction, just use an assign to map the response with the output.
5. Once done, drag the DataAction output to the screen and create the layout.
