As per filament documentation created a new file at app/Filament/Pages/Dashboard.php and also remove the original Dashboard class from filament.php
Dashboard.php File Code: (https://i.stack.imgur.com/39INc.png)
filament.php File Code:
'pages' => [
'namespace' => 'App\\Filament\\Pages',
'path' => app_path('Filament/Pages'),
'register' => [],
],
After following these steps, I am facing these issues getting the Dashboard option multiple times in the sidebar.
