Use as Agent Tool

Multiple actions can be selected to let the Agent intelligently choose the appropriate one. Parameters can be left empty to allow the Agent to determine the values on its own. However, if the user provides values, those will override the Agent's choices.

Use as Tool Node

It can also be used as a Tool Node in a determined workflow scenario. For example, retrieving a list of Teams messages before proceeding to the next step. In this mode, Tool Input Arguments must be explicitly defined and filled with values. Unlike the Use as Agent Tool option, there is no Agent to automatically determine the inputs. The user must manually populate the fields, either by entering fixed values or using variables enclosed in double curly brackets {{ }}.
