let response = {
  "status": true,

      {

const collaborators = response.data.collaborators.filter(c => c.supportNotification);

This will give you each collaborator object that has supportNotification = true. Is this the result you are trying to select?

var body = {
  status: true,
  date: "2022-04-06T16:33:13.630Z",
  data: {
    collaborators: [
      {
        name: "Paul",
        lastCheckin: "2022-03-31T19:54:50.584Z",
        sales: 1,
        createdAt: "2022-03-30T14:47:48.478Z",
        id: "62446d4ab7f4da001e8f40dc",
        supportNotification: true,
        collaboratorId: 1,
      },
      {
        name: "John",
        lastCheckin: null,
        sales: 0,
        createdAt: "2022-03-01",
        id: "62446ea4b7f4da001e8f40df",
        supportNotification: false,
        collaboratorId: 6,
      },
    ],
    count: 2,
  },
};

var result = [];

body.data.collaborators.forEach((item) => {
  if (item.supportNotification === true) {
    result.push(item);
  }
});

console.log(result);
