'Why is Dialogflow CX referencing gcloud's project (project-number)?

I am working the Dialogflow CX Java SDK to execute a list agents command. When, I try to list the agents, I get this exception.

io.grpc.StatusRuntimeException: PERMISSION_DENIED: Dialogflow API has not been used in project project-number before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/dialogflow.googleapis.com/overview?project=project-number then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.

Relevant code snippet:

AgentsSettings agentsSettings = AgentsSettings.newBuilder().build();

AgentsClient client = AgentsClient.create(agentsSettings)
LocationName parent = LocationName.of("my project id", "US-CENTRAL1");
AgentsClient.ListAgentsPagedResponse agents = client.listAgents(parent);

Any help appreciated.

This error may indicate that the GOOGLE_APPLICATION_CREDENTIALS and/or GOOGLE_CLOUD_PROJECT environment variables were not properly set. Reviewing the Dialogflow CX Setup documentation may help.
