Hello @kartik,
You can put this code for example in controller.
You can use
$user = User::find($id);
$user->delete();
if you don't use SoftDeletingTrait trait or
$user = User::find($id);
$user->forceDelete();
if you do, and you want to really remove user from database, not just hide it from results.
Hope it helps!!
Thank you!!
