Get the 2nd Friday of a month with MomentJS

I am trying to get the nth Friday of a month with momentjs

where n is in the range [1,4]

So if a user supplies n as 2. Then I need to get the date for the second Friday of the month.

Here is what I tried with no sucess

let startingFrom = new Date("StartDateStringGoesHere");
let n=2;
let nthFriday = moment(startDate).isoWeekday(n); //I can't figure out how to resolve it here

Any ideas will be truly appreciated.
