In the topic, we can add a tool and select Connector > Nimbus > Update Task

⮑ This adds the Update Task activity to the topic flow. 

Within the “Update Task” activity we simply need to reference the Task Id and hand over the data.

☝Pay attention to data types. You can ask Copilot 365 to create your Powerfx formulas if you are unsure how to transform your data.

i.e. we can set the Custom Context Parameter which needs a Table object in Copilot Studio.

Table(
 { name: "Sentiment", value: Global.sentiment },
 { name: "Language", value: Global.Language },
 { name: "Topic", value: Global.Topic },
 { name: "Urgency", value: Global.Urgency },
 { name: "Message", value: System.Activity.Text }
)
