Why is ascii2str not recognized in 2022a?

This clip fom the command window summarizes my question. I hav a new install of MATLAB 2022a on MacOS 12.4. Has something changed?

>> bytes = [0x57 0x58 0x53 0x54]

bytes =

  1×4 uint8 row vector

   87   88   83   84

>> str = ascii2str(bytes)
Unrecognized function or variable 'ascii2str'.

According to the documentation "The operator ascii2str is supported only in Stateflow® charts that use C as the action language."

In MATLAB the equivalent is the char function.

bytes = [0x57 0x58 0x53 0x54]

bytes = 1×4

87 88 83 84

c = char(bytes)

c = 'WXST'
