Currently, the search tool allows you to search for “Uses API” but it only search for uses of external APIs such as Google APIs.
Searching for uses of API Workflows must by done by using Search by Action type.
This requires two searches to find all references:
Action type “Schedule API Workflow”
Action type “Schedule API Workflow on a list”
As a result, you cannot be sure you’ve found every use of an API workflow in a single search.
This is tedious and error-prone.
