Salesforce Fact #935 | Get country prefix using screen action

We can show the country prefix code with the help of screen action.

In this example, we have created a custom metadata to store the country code and respective prefix value. Now, in the screen flow, on selecting a country picklist value we can pass the entire metadata list and the selected country value to a subflow in order to get the prefix and show the same in the screen instantaneously. 

Attached are the screenshots.
