Getting "'Emulation.setCPUThrottlingRate' wasn't found" error on Mac and Windows os when trying to set this in the Protocol Monitor tab in chrome

Question

I'm trying to simulate CPU throtling by puttin this command:

{"command":"Emulation.setCPUThrottlingRate","parameters":{"rate": 20}}

In the chrome dev tools protocol monitor tab. Tried either on Mac and Windows os. Getting this error:

{
    "code": -32601,
    "message": "'Emulation.setCPUThrottlingRate' wasn't found"
}

Chrome version:

Version 122.0.6261.112 (Official Build) (arm64)

Any suggestions how to fix this would be appreciable. Thank you.
