I am trying to detect my stm32wba52cg bare chip 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.

What do you mean by that - Literally a bare chip; no PCB at all?  A custom PCB ? Other?
