How can I check for a bedrock action group invocation?

[peterklipfel]

We have an agent with a number of action groups. When running a simple test, the agent responds correctly in the trace:

...
          {
            "orchestrationTrace": {
              "invocationInput": {
                "actionGroupInvocationInput": {
                  "actionGroupName": "{{MyActionGroup}}",
                  "executionType": "RETURN_CONTROL",
                  "function": "{{the-function}}",
                  "invocationId": "{{some id}}",
                  "parameters": []
                },
                "invocationType": "ACTION_GROUP",
                "traceId": "{{some id}}"
              }
            }
          }
...

However, the results that I get from the execution are:

Steps

1. Ask agent for {{the visualization}}.

Expected results

1. Agent calls {{MyActionGroup}} action group with function {{the-function}}

Conversation

[USER] Can you please show me {{the visualization}}?
[AGENT] 

Result
Not all of the expected results can be observed in the conversation.

Reasoning

To determine if the expected result can be observed in the conversation, I need to check if the agent called the {{MyActionGroup}} action group with the `{{the-function}}` function in response to the user's request to show {{the visualization}}.

Since the agent's response is blank, it does not appear that the expected action was taken. Therefore, not all of the expected results can be observed in the conversation.
