Why am I recieving a warning when importing a "struct" with a 2-D array using "Simulink.​importExte​rnalCTypes​"?

I am attempting to import a header file into Simulink in MATLAB R2022a using the following command:

>> Simulink.importExternalCTypes("test.h")

The header file defines a struct in C code, which contains a 2-D array member, as shown:

typedef struct myStruct{
    float y;
    float x[2][2];
}myStruct;

However, I receive the following warning: 

Warning: 'myStruct' from file 'C:<currentDirectory>\test.h' is not imported. It has a field whose type is unsupported in Simulink.

Why is the import not working as expected?

N-dimensional arrays in structs were previously unsupported in MATLAB R2022a, so the warning is expected behavior.

Importing multidimensional arrays is supported in R2022b onwards, please update to this or a newer release to access the latest functionality.
