Can you tell me if usernames and password are transmitted in clear text when actions such as the "Start Workflow" and all the Office 365 actions execute? I don't quite understand the notes in the documentation when it is mentioned that start workflow may not be bounded by the tenant. Perhaps someone can provide some clarification:
"This action is not fully bounded by your Office 365 tenancy. It either calls outside of the tenant or executes on servers potentially running outside your region. Before implementing, consider performance and regional concerns where digital boundaries are an issue."
