I'm trying to hide prices and "add to shopping cart" for guests.

To do that I need to check whether the customer is logged in or not. There are no predefined methods in the Catalog Widget block so I need to extend the class via preference.

I've successfully extended the block Magento\Catalog\Block\Product\ListProduct but Magento\CatalogWidget\Block\Product\ProductsList is trickier.

When I try it, I get main.CRITICAL: Invalid template file: 'product/widget/content/grid.phtml' in module: 'Vendor_Namespace' block's name: 'product\productslist_0' in system.log.

Any solutions to this?
