What do you mean specifically? You can use ReminderScheduled events to schedule messages for a later time. Apart from that, the user always has to initiate the conversation.
I think the most similar i am asking for is Events
Situation: i don’t know particular time to schedule event, i only want to resume conversation in case user stop posting to bot for 5-10 sec. That means he want to leave conversation or bored of stupid bot when you always need to ask him, but bot never ask user of something
But, i cannot invoke this event after every question, only in case user hangs 5-10 sec
that’s something you could only really do with the ReminderScheduled event. I don’t think it’s really good practice to constantly prompt the user after 5-10 seconds though
