Let's assume the variable {{example}} outputs the values 'KEY-1, KEY-2, KEY-3, KEY-4'. This variable is created to store object keys from lookupObjects.
Using the split function or other text string functions, how can we split the content of the variable {{example}} in half so that the first part {{part1}} outputs 'KEY-1, KEY-2' and the second part {{part2}} outputs 'KEY-3, KEY-4'?
The solution should be applicable regardless of how many keys {{example}} contains, whether it be any number between 1 and 100.
