I am trying to detect my stm32wba52cg bare chip with my developed custom PCB board with onboard stlink as external programmer from a discoveryboard but its showing this msg-

Can not connect to target!
Please select "Connect Under Reset" mode from Target->Settings menu and try again.
If you're trying to connect to a low frequency application , please select a lower SWD Frequency mode from Target->Settings menu.
No target connected.

this are my connection for programming my wba52 controller-
