Help with Gui with a Keybind

[forest gust]

I am trying make a inventory-like Gui appear when the player press a button but after i followed a tutorial, it seems i got stuck with the code being a container for a entity instead of a inventory

The "CharmScreenHandler::new" is the one with the red underline mark

public class ModScreensHandlers {
    //public static final ScreenHandlerType<CharmScreenHandler> CHARM_SCREEN_HANDLER =
    //       Registry.register(Registries.SCREEN_HANDLER, Identifier.of(HollowKnight.MOD_ID, "charm_screen_handler"),
    //               new ExtendedScreenHandlerType<>(CharmScreenHandler::new, BlockPos.PACKET_CODEC));
    public static final ScreenHandlerType<CharmScreenHandler> CHARM_SCREEN_HANDLER =
            Registry.register(
                    Registries.SCREEN_HANDLER,
                    new ExtendedScreenHandlerType<>(CharmScreenHandler::new)    
            );

    public static void registerScreenHandlers() {
        HollowKnight.LOGGER.info("Registering Screen Handlers " + HollowKnight.MOD_ID);
    }
}```

        addPlayerInventory(playerInventory);

    }```
