Description

• Implement the editor notifications page https://www.figma.com/design/0R2sZFZQJd9iPiOJ2LzVTR/Easy-sharing-of-community-channels?node-id=1354-31700&t=6L5ybOfI7T4FHsm4-0.
  • Implement it as an Immersive page.
  • Ensure that the notifications page is still present if the user reloads.
  • We won't build the "unread" and "all notifications" tabs logic for now. We can also skip the options button for now.
• Use the useFilter composable to update the filters.
• Search notifications using a debounce function when using the search field.
