Hi @akshay thanks for chiming in here! There was a similar question recently in this thread [Restoring columns in "Custom Fields"?] around restoring custom user fields.
Right now, users cannot restore these fields like you can in normal tulip tables, but the Tulip Team is working on improving that functionality.
For now, anyone who needs to restore fields from the custom user fields can contact our support team at tulip@support.co and they can help restore those fields!
