object (TemplateFunction)

Optional. A list of user-provided functions for function calling. For functions whose names are listed in the template frontmatter, the model may decide to call a subset of these functions by populating FunctionCall in the response. User should provide a FunctionResponse for each function call in the next turn.
googleMaps

object (GoogleMaps)

Optional. Tool to retrieve public maps data for grounding, powered by Google.

TemplateFunction

This is a representation of a block of code that can be used as a Tool by the model and executed by the client. The name of the function must be listed in the template frontmatter for the model to be able to call it.
