Count previous month items

Hi i am creating a metrics for a Dashboard and i just need a count of new items that were created in the previous month. I am using as base the "created date" column. For your reference i already have one that is counting the items created during the current month and it is working. What i don't know if where to include an argument to change to previous month.

This is the formula that i have now for current month count

=COUNTIFS({What is it?}, "Issue", {Created date}, AND(IFERROR(MONTH(@cell), 0) = MONTH(TODAY()), IFERROR(YEAR(@cell), 0) = YEAR(TODAY())))
