is there any way to add mark to tracker store for end session in database?
There isn’t an end session event. You could create your own custom action.
You may also want to look at the new markers feature to see if this will address your use case.
I just find quiet same problem and i think the solution can be solve with that kind of way by using reminders Ended action session
You have to be careful with reminders because a restart of Rasa loses all reminders. It’s not really a production ready feature.
I see, thanks for the suggestions
