midi.getSysExArray usage explanation

Hi, I'm trying to extract data from a MIDI System Exclusive message.
I know I need to get the data into a form that lets me read the bytes I need, but first I need to capture the data.
There is a midi.getSysExArray function in the MIDI library, but there is no explanation on GitHub of how to use it. The only information is: const byte * MIDI_Class::getSysExArray ( ) const. Can someone explain what that means or point me to another source of information?
Thanks

Hello

Try something like this

byte * arr = midi.getSysExArray();
size_t len = midi.getSysExArrayLength();

for ( size_t i = 0; i < len; i++ )
{
  Serial.println( arr[i] );
}

Thank you for your reply, but I'm looking for an explanation of how to use the function.
What does the code you sent mean and what does it do?
