Mini STM32F103C8T6 CH340

Hi,
I'm new to stm32 mcu. I got this Mini STM32F103C8T6 CH340 board from Alipexpress (https://fr.aliexpress.com/item/1005006910706030.html)
Thanks to the embedded CH340 uart, I thought I should be able to program it directly from the Arduino IDE. But I'm a little bit confused regarding the settings in the Arduino IDE for this board.
Is there anybody with experience on this board?
Who could give me the whole process to upload a program on this board?
What is the correct additionnal board url to use? I found 2:
-http://dan.drown.org/stm32duino/package_STM32duino_index.json
-https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmicroelectronics_index.json
And then which board/part number to select? Which upload method?
On the board itself: what is the correct way/order to press the buttons?

Thanks for your help

    If the vendor doesn't provide any instructions, you should probably pick something similar / generic

    You likely need to use the RST+BT0 button to reset into the system loader, supporting the UART / AN3155 protocol. And use STM32 Cube Programmer or stm32loader to push in the binary image.

    You get one shot per reset

    Thanks a lot for your help.
    I installed STM32 Cube Programmer and it works!
    Arduino IDE settings:

    -additionnal board url: -https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmicroelectronics_index.json

    -Board selection: Generic STM32F1 series

    -Board part number: Generic F103C8Tx

    -Upload Method: STM32CubeProgrammer (Serial)

    Then BT0+RST buttons to set the board in upload mode. Upload in Arduino IDE and that's it.
