ESP C3-F12-Kit I2C configuration

[zaik2rlm]

Sorry, I'm a newbie, I wish I could use I2C on an ESP C3-12F-Kit, but I can't.
I'm using an ESP32 TTGO with I2C without problems, but this one has a dedicated GPIO21 & GPIO22 as I2C channel, while I've read that with ESP C3-12F-Kit one can configure the ports he most wants, the problem is that after several attempts I'm not managed to configure the I2C, is there anyone able to give me an example.
