Multiple smaller questions about events and such

[Haaxor1689]

I have decided to make an addon to speed up Abah's watch motif farming. I would like to solve some issues and currently don't know how:

1. How can I close a chatter?
I have an EVENT_CONVERSATION_UPDATED callback, that get's called when you enter the 2nd chatter screen with the turn in nps, where is only "goodbye" option. How can I close this automatically?

2. How to open the quest reward container?
I am auto completing the quest with EVENT_QUEST_COMPLETE_DIALOG callback and then by calling the CompleteQuest function. How can I then open the quest reward?

3. Is it possible to automatically interact with object I have reticle on?
With current implementation, player needs to just spam the interact key, while unwated dailies from tip board are abandoned and the desired one is kept. Is there a way to automatically just interact with the board?

4. How to check if a quest is in players journal at addon load?
I would like to register for EVENT_CHATTER_BEGIN only if the quest is active. This needs to be done in init, in case player reloads the UI, but my callback is unnecessarily called all the time.

I would be really glad if you could answer any of my questions Thanks
