How to access the tracker_store and tracker in actions.py file in Latest rasa version

def slot_update(tracker, key, value): from api import agent events = [SlotSet(key, value)] for e in events: tracker.update(e) agent.tracker_store.save(tracker)

This code I used to use for savings some slot values in rasa 0.9 version. But current rasa version is 1.8.2 in which how do I access the tracker and tracker_store manually?. Because I have to set few slots manually in actions.py file.

Please help me out, any early help would be highly appreciated.
