Minimum connections needed between stm32 MCU and the st-link programmer?

My MCU is stm32L432kc. I've concluded that we need a minimum of 4 connections: SWCLK, SWIO, vcc and gnd. Can someone from here confirm that?

And another question is I'm confused how to connect the Vdda/Vref+ pin 5 and the NRST pin4. Do I have to connect them? I have the schematic of nucleo board for my MCU attached. Should I just connect them the same way?
