Deleting CollectionNodes at runtime

Question

I am doing an app where there is a need for multiple (number is arbitrary) independent group chats. I first tried to solve this by using 'nodes' inside a single 'collection node' but found it does not scale, because every user is getting every message for each group regardless he is 'in' that group or not. The solution that came to my mind is to create new collection node for each group. I am going to handle this problem by creating a common collection node to which all user subscribe initially, this collection node contains some auxiliary information about the ongoing chat groups.
Once a user starts a group chat, app creates a new collection node then sends a notification to invited users on common collection node. Invited users then connects to that newly created collection node for group chat. This way messages are transferred among users in that group only. At the end of that group chat, I need a way to delete that collection node. I looked at AFCS API, but did not find a way to do that, I guess there must be one because in AFCS Dev Console we can delete collection nodes.
Requested Feature:
AFCS API should provide a way to configure collection nodes similar to 'nodes' plus an inactivity timeout feature i.e. during collection node configuration developers can set an inactivity timeout value and once that inactivity timeout is reached AFCS servers notify users subscribed to that collection node and delete it.
Thanks

Hi,
Please explore RootCollectionNode for information about deleting collection nodes. You need to be the owner of room to delete the collection Node. From your use case try re-using SimpleChatModel if it would work for you. (Assigning it a different sharedId would do the trick)
Thanks
