Extractregexall help

Questions and Help
1

when using extractregexall all, is there a way to then extract only the second expression if there are only 2 expressions pulled?

For example if my extractregexall all pulls this ["100331026", "77203890"]

is there a way for it to pull just the 772038990?

To pull the last item in the list, use the -1 index:

{list=["100331026", "77203890"]}
Last item: {=list[-1]}
