Microsoft direct line bot integration

Dev
1

Hi,
I’m developing an voicebot (not ws) integration with microsoft bot service (direct-line). There is not a standard integration within Pipedream.
Although, I’m doing it myself and the start of a conversation starts in more than 6 seconds (sometimes more). This is time that user is waiting on the phone.

To start a conversation the direct-line integration needs 3 requests as specified here https://docs.microsoft.com/en-us/azure/bot-service/rest-api/bot-framework-rest-direct-line-3-0-start-conversation

1 Open a new conversation
2 Start conversation
3 Retrieve data (string of what to be said) from first activity

Is there a way to do all three on a single request? Doing them on a single step will be faster?

Thanks
