delete keys from a nested object from an array of keys

I have a very large array of objects that I need the keys remove from. I can’t seem to get my head around how to make this happen with list of keys.

const sections = [
            {
                municipality: "Monte De Oca",
                office: "Oficina de la Mujer"
            },
            {
                case_number: "MDO-ABCDEFG",
                identification: "Cédula",
                id_number: "123456789"
            }
];
    
const removeThis = [
    "municipality",
    "id_number"
]


function filter(data) {
  for(var i in data){
    if(removeThis.indexOf(i) != -1){
       delete data[i]; 
    }
  }
  return data;
}

console.log(filter(sections));
