 3. **Active filter:**
    - `PresetTag`: Matches chat type and characteristics (e.g., `CONTACTS` filters `ChatInfo.Direct`, `GROUPS` filters `ChatInfo.Group`).
    - `UserTag`: Matches chats whose `chatTags` contain the tag ID.
-   - `Unread`: Matches chats with `unreadCount > 0` or `unreadChat == true`.
