Update sender_id of tracker with a channel_id from slack

Hello everyone, I would like to override the sender_id from the tracker with a channel_id from Slack. For this, I would have an approach by overriding the “update_conversation_with_events” function from DialogueStateTracker Objects. However, I don’t know where to call this function in my custom_action. Has anyone ever had an experience with overriding the methods?
