See the SS website, https://www.ssa.gov/benefits/retirement/planner/applying7.html#h4
This page discusses benefits for a divorced spouse.
That page says "If you have not applied for retirement benefits, but can qualify for them, your ex-spouse can receive benefits on your record if you have been divorced for at least two continuous years."
So the two important considerations for you are (1) ex-spouse does not need to be actually collecting their SS benefit at the time you collect and (2) if in such case you have been divorced for at least the 2 years they describe...which you meet.
Good luck.
