I have tested it with esp32 as you can read on the homepage of this project. Your issue description does not give any information, so I don't know how to help you.
Which boards did you use. How did you connect. Which example did you run. What was the output?

Hi, this helps. It means you have the basic app installed, and you have the lib installed.
You compiled them, and run them. But the app cannot connect to the hardware.
I suspect wrong wires, broken wires, or, worst case, a broken sensor.
Would it be possible to show me photo's of the wires. Where do the wires connect to the ESP, and where do they connect to the ccs811. Assuming you use wires of different colors, a zoomed-in photo on the ESP side and a zoomed-in photo on the css811 side and a zoomed-out photo where everything is visible would be great.
Do you happen to have a logic analyser or scope? A great test is to put that on the pins of the CCS811 and check they have the correct signal.

It could be another 'feature'. I have the same problem and I solved it by two things
- use wire.begin with defined pins e.g.
Wire.begin(19, 23);
see #29 The ESP32 does not have specific I2C pins. - hard reset of the vcc rail for the I2C sensors. The CCS811 somehow is a little bit picky about the initialisation.
