Enatega Customer Application : Missing Reload Function on "Discovery" Page When Scrolled Down

Describe the bug
When the customer opens the app then on the discovery page if he refresh the page there is no action been showing up there for confirmation that the screen is reloaded or not. This results in the inability to refresh the content when reaching the bottom, affecting the user experience.

To Reproduce
Steps to reproduce the behavior:

Go to 'Enatega Customer Application'
Now go to Discovery screen.
3.Pull down to Refresh the screen, Observe the screen – no confirmation or action appears to indicate that the screen has been reloaded.
Expected behavior

A loading spinner or progress indicator (e.g., a circular spinner at the top of the page) should be displayed while the refresh is in progress.
Once the refresh is complete:
The page should visibly update with refreshed content (if any changes exist).
Optionally, a toast notification (e.g., "Page refreshed successfully") can be shown for confirmation.
If there is an error during the refresh (e.g., no internet connection), a toast message or an error indicator should be displayed, such as:
"Failed to refresh. Please check your connection and try again."
