RAK3172-E - Working with STLink and CubeProgrammer

I have a RAK3172-E and I want to load to it my FW that is running on the STM32WL Nucleo board.
For that I need to connect to the RAK3172-E with my STLink
Can you please list the connection that I need to use for that?

Here is the connection diagram for STLink to STM3172 stamp module:

The required pins SWDIO, SWCLK, RST, GND and 3.3V are on the RAK3372 stamp module accessible:

If you power the Evaluation board over USB, you do not need the external 3.3V supply.

Thank you for your quick reply.
I connected the STLink to the board like above but the CubeProgrammer does not able to connect and I get an error message: Error: No STM32 target found!
I tried both to supply the voltage from the STLink itself as well as from the USB and also from a power supply and I get the same error again.
Any idea what might be wrong?

OK, Success
The VCC pin 1 on the STLink is actually VTRef and if I connect it in parallel to the USB then the CubeProgrammer succeed to connect
