Repeater: show delete button on each line conditionally

I am trying to let the user only delete repeater records with certain data conditions. Currently I only managed to stop the delete action but I think there must be a way where I can even conditionally show/hide the delete button based on the data within the record.

Repeater::make('Links')
    ->relationship('weblinks')
    ->schema([
        TextInput::make('url')
            ->url()
            ->disabled(fn (Get $get) => !Weblink::typeEditable($get('type'))) //readonly on some types
            ->dehydrated(),
        Select::make('type')
            ->options(Weblink::getSelectWeblinkType())
            ->disabled(fn (Get $get) => !Weblink::typeEditable($get('type')))
            ->dehydrated()
    ])
    ->addActionLabel('New Link')
    ->defaultItems(0)
    ->deleteAction(function (Action $action) {
        return $action->before(function ($state, $arguments, $action) {
            if (isset($state[$arguments["item"]])) {
                $item_id = Arr::get($arguments, "item");
                $item = Arr::get($state, $item_id);
                $type = Arr::get($item, "type");
                if (Weblink::typeEditable($type)) {
                    return $action->hidden(false);
                } else {
                    Notification::make()
                        ->title('Error')
                        ->body("Type not allowed")
                        ->status('danger')
                        ->send();
                    return $action->cancel();
                }
            }
        });
    })

I tried to make a similar condition in function Repeater->deleteable(function (...)) but here I don't have access to the $arguments, so I cant say which element of the state I am currently processing.

Still the current solution I showed above is working for me but it feels wrong. I think there is a much easier way, I am just not seeing it yet probably.
