How to use both 2 I2C interface on StickC-Plus2?

Env PlatformIO

platformio.ini:

...
platform = espressif32
board = m5stick-c
framework = arduino
...
lib_deps =
	Wire
	m5stack/M5Unified
	m5stack/M5Unit-DDS

Question:

I connect 2 modules to StickC-Plus2, one on 'grove' port, the other on 'Ext.8-pin'. Is it correct to connect this way( or to say, is it possible to communicate with 2 modules through I2C separately through GPIO25-GPIO26 and GPIO32-GPIO33)? If this is correct, then how should I write the code?

Currently in my code, I defined the second 'TwoWire' object and initialized a module with it, but communication failed, while default 'TwoWire(0)' works well.

TwoWire I2C_DDS = TwoWire(1);

...
	I2C_DDS.begin(DDS_SDA, DDS_SCL);
	dds.begin(&I2C_DDS);
...

Look at the definition of TwoWire, number should be fixed
