[nuno-vieira]

🔗 Issue Links

Resolves https://github.com/GetStream/ios-issues-tracking/issues/787

🎯 Goal

Adds the new reactions v2 query endpoint to be able to filter reactions based on type and author.

📝 Summary

• Adds new ChatReactionListController
• Adds new Slack Reactions List View to the Slack Example app

🛠 Implementation

Creates a new ChatReactionListController to follow the SDK pattern, where each query endpoint represents a controller.

TODO:

• [ ] Everything is tested besides the ReactionListController.
• [ ] Website docs for the new reaction list controller

🎨 Showcase

🧪 Manual Testing Notes

Note: Backend user enrichment is not working on the new query reactions endpoint. So this is not testable until it is fixed on the backend.

1. Open the Slack Example App
2. Go to a channel
3. Long press on a reaction
4. It should show only the reactions of that type.
