How to limit comment when get feed and filter reaction

[toannv1803]

1. I use this code to get feed

timeline.get({ 
  ranking: '...',
  enrich: true, 
  limit: 3,
  recentReactionsLimit: 2
  ownReactions: true, 
  withOwnReactions: true, 
  withOwnChildren: true, 
  withReactionCounts: true, 
  withRecentReactions: true, 
})

I receive 3 activities, in every activity has 2 comments lv1 but unlimited comment lv2 in comment lv1 return in the result.
Getstream support create reaction lv 0, 1, 2. When I get feed how to I limit reaction lv 1, 2

2. When I filter reaction, latest_reactions include all reaction child, I can't limit data in latest_reactions.
   This is my code

client.reactions.filter({
  activity_id: activityId,
  kind: "comment",
  limit: 1
});

3. When I load more comments, I use filter reaction, but I can't get own_children of the current user.

Thank you.
