Get object keys using another object

I would like to receive every user id that got the object {"cool": true}. So in this case these would be 681980629554137898 and 953522081637941260.

My JSON file:

{"681980629554137898": [{"id": "681980629554137898"}, {"cool": true}],
"790606386957778984": [{"id": "790606386957778984"}, {"cool": false}],
"953522081637941260": [{"id": "953522081637941260"}, {"cool": true}]
}
