for pseudo code on the usage.
May I ask how you are using the CMSIS-NN APIs? the intention is to use it along with TFLM and the list of operators supported are in the link attached. If you are using tflite files along with TFLM's interpreter, then handling of all operators(provided they are supported) will be handled by TFLM's interpreter. That goes for concatenation as well.
