Iterate json body multiple times

hi ,

I am new to Gatling. My scenarios is to post the request.where one user logs in and post 25 or 50 request at one shot

my json looks like this

“leader_availability_status”: “Approved”,
“total_voluntary_availability_requests”: 1,
“voluntary_availability_request”: [
“last_updated_timestamp”: “2019-05-07 15:54:00”,
“status_change”: “2019-05-07 15:54:00”,
“status_timestamp”: “2019-05-07 15:54:00”,
“voluntary_availability_request_id”: XXXXX,
“voluntary_request_status”: “Submitted”

I am passing request_id from csv, but not sure how to iterate the body mulitple times with values from csv
