Questions about the ATmega2560 footprint

parts help
1

In my current PCB project, I want to use an ATmega2560 microcontroller. The chip has multiple GND and power pins. However, in the Fritzing schematic view, only one pin is available. In the PCB view, all pins are present. When I connect the chip in the schematic, the additional pins in the PCB view are left unconnected — floating in the air — which is not acceptable. Manually connecting them afterwards in the PCB view is certainly not the right approach. So my question is: are the pins hidden, can I enable them, or is there a version of the component that includes all pins?

Update: In the breadboard view, the required pins are present. Sorry, I had never used the breadboard view before. When I connect the relevant pins here, I also get the required connection in the PCB view. Maybe not the most professional solution, but it works for me.
