Determine do I have MCU from CH32X033 family

[vido89]

I have on board MCU without marking on it the VDD and GND maches to CH32X033F8P6 or CH32X035F7P6
so is there a way to determine do I have CH32X033F8P6 or CH32X035F7P6 on my borad ? TNx

The only option I see is to somehow connect the MCU with a WCH-LinkE and check if communication with the MCU is possible. But please keep in mind that there are probably hundreds of MCUs in the same package, and they often have similar pinouts.
