I just recently success managed to try it using a BluePill board. I was using Arduino IDE v2.1.0, board manager: STM32 MCU base boards by STMicroelectronics v2.6.0, upload method: ST-Link v2.
Here is the configuration of the menu order I clicked on:

1. [Tools] > [Board] > [STM32 MCU base boards] > [Generic STM32F1 series]
2. [Tools] > [Board part number] > [BluePill F103C8] / [BluePill F103CB (or C8 with 128k)]
3. [Tools] > [Upload method] > [STM32CubeProgrammer (SWD)]
4. [Tools] > [USB support (if available)] > [CDC (generic 'Serial' supersede U(S)ART)]
5. [Tools] > [U(S)ART support] > [Enabled (generic 'Serial')]

Try using "Serial1" instead of "Serial" if using a USB to TTL converter module (based on my Win 10 experience).
