I have created a Logic apps custom connector (SOAP pass-through). I then created a new Logic App and when I go to the designer, create a trigger (recurrence) and attempt to add a second operation (the custom connector), the custom connector cannot be found in the 'Search connectors and actions' search box. The options for a new operation are 'Built-In' and 'Azure'. Is there something I'm missing here, the documentation is very brief for using custom connectors is a Workflow.
