• We need to create a new channel details module inside the modules folder.
• The new channel details page will replace the old channel details page on /channels/:id route.
• This page should list down the channel logos in the left.
• It should render all the channels details mentioned in the designs
• It should all the user to subscribe and unsubscribe the channel from the button.
  NOTE: We need to use the new subscribe/unsubscribe dropdown here which we are suing the dashboard page.
• It should render the recent 20 notifications.
  -For now we will use the same notification card. But will update those cards in separate tickets once we have done the changes in the sdk.
• The css notification cards coming from the sdk should match the new designs in ticket.
• User should be able to switch between channels when they click on the channel icon in the left.
