USBSerial.print('A'); causes compile error

[teastainGit]

Describe the bug

(Similar to Sarah-C three weeks ago but I uninstalled ver 2.0.5 and re-installed.)
Library >Arduino15 › packages > m5stack > hardware > esp32 >2.0.6
No other old M5Stack versions left over.
Deleted the AtomS3 Library and re-installed fresh from your repository.)

PROBLEM:
In the example from your GitHub repository "Button.ino" (and all the examples) produces a compile error:

                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

/Users/terrystainton/Documents/Arduino/libraries/M5AtomS3-main/examples/Basics/Button/Button.ino: In function 'void loop()':
/Users/terrystainton/Documents/Arduino/libraries/M5AtomS3-main/examples/Basics/Button/Button.ino:32:9: error: 'USBSerial' was not declared in this scope
USBSerial.print('A');
^~~~~~~~~
/Users/terrystainton/Documents/Arduino/libraries/M5AtomS3-main/examples/Basics/Button/Button.ino:32:9: note: suggested alternative: 'Serial'
USBSerial.print('A');
^~~~~~~~~
Serial

exit status 1

Compilation error: 'USBSerial' was not declared in this scope

Perhaps there is a local cache package that is not downloading the latest M5Stack version definition
Please delete the following path, uninstall the M5Stack 2.0.6 definition and try again
/Users//Library/Arduino15/staging/packages
