Filament: Custom Title or Description in Action Confirmation Dialog

When dealing with Actions in Filament, you might have seen ->requiresConfirmation() added like this:

Tables\Actions\Action::make('Set as Default')
    ->icon('heroicon-o-star')
    ->hidden(fn($record) => $record->is_default)
    ->requiresConfirmation(),

What if we want to add a custom message to the confirmation dialog? We can do that by adding a closure to the requiresConfirmation() method like this:

Tables\Actions\Action::make('Set Default')
    ->icon('heroicon-o-star')
    ->hidden(fn($record) => $record->is_default)
    ->requiresConfirmation(function (Tables\Actions\Action $action, $record) {
        $action->modalDescription('Are you sure you want to set this as the default pipeline stage?');
        $action->modalHeading('Set "' . $record->name . '" as Default');
 
        return $action;
    })

You can set whatever message you want and even use the record data to make it more dynamic.
