AdaFruit and others make a LTC4311 extender but they use qwiic smaller connectors but same pinout.
I2C is designed for sensors close to the controller and 1 - 2 meters is the limit. The LTC4311 gives a little more but after that you should consider RS485.
M5Stack make several of these:

I2C to 485 transceivers.

I can’t buy m5stack version of i2c extender because it doesn’t exist.
