Welcome,@SDavi.6, to the community!
Well, even if you cite the sources, I question their statement because the STM32CubeIDE only supports STM32 from STMicroelectronics. However, the RA-08 module from Ai-Thinker uses the ASR6601 chip from the Chinese manufacturer ASR, as you can read in its description, which has absolutely nothing to do with STM32:
Ra-08-Kit is a LoRaWAN development board designed and developed by Shenzhen Ai-Thinker Technology Co., Ltd. [...]
The chip ASR6601 on the development board is a general-purpose LPWAN wireless communication SoC that integrates an RF transceiver, a modem and a 32-bit RISC MCU. The MCU adopts ARM core, and the operating frequency can reach 48MHz. [...]
