@Kajol-Kumari Can you please check my PR and merge it.

[Kajol-Kumari]

please modify this to be generic i.e if the api is success, it should show success message and if api fails, it should show error message. please take reference from - https://github.com/HITK-TECH-Community/Community-Website/blob/main/frontend/src/pages/ContactUs/ContactUs.jsx#L324-L328

Also, when i am adding the member using ui, the image isn't appearing in the fetched list, please look into that as well, its a level3 issue, i expect it to be working e2e.
