Feature Request: Implement Pagination for Channels/Groups Fetching

[abela12]

Our app currently loads all channels and groups together, causing slow performance as the list grows. To fix this, I suggest using pagination.

This means loading a set number of channels or groups at a time and loading more as the user scrolls. It's called "infinite scroll" or "lazy loading." This change will speed up the app's initial load time and make it more responsive as users navigate through channels and groups.
