How to modify array structure returned by eloquent in laravel

I currently have the below array structure that I get when running Bonus::with('users')->get()

I have tried adding the array and merging similar keys but it is not working. I tried using the helper methods provided in laravel but I don't seem to be able to get it working.

[
{
"id": 1,
"users_id": 1,
"bonus_type_id": 1,
"is_paid": 0,
"amount": "100.00",
"description": "desc",
"note": null,
"created_by": 2,
"last_modified_by": null,
"created_at": null,
"updated_at": null,
"deleted_at": null,
"user": {
"id": 1,
"name": "test",
"email": "test@testing.com",
"email_verified_at": null,
"status": 1,
"created_at": "2019-07-18 11:41:35",
"updated_at": "2019-07-18 11:41:35",
"deleted_at": null
}
},
{
"id": 2,
"users_id": 1,
"bonus_type_id": 2,
"is_paid": 0,
"amount": "100.00",
"description": "desc",
"note": null,
"created_by": 2,
"last_modified_by": null,
"created_at": null,
"updated_at": null,
"deleted_at": null,
"user": {
"id": 1,
"name": "test",
"email": "test@testing.com",
"email_verified_at": null,
"status": 1,
"created_at": "2019-07-18 11:41:35",
"updated_at": "2019-07-18 11:41:35",
"deleted_at": null
}
},
{
"id": 3,
"users_id": 2,
"bonus_type_id": 2,
"is_paid": 1,
"amount": "100.00",
"description": "desc",
"note": null,
"created_by": 2,
"last_modified_by": null,
"created_at": null,
"updated_at": null,
"deleted_at": null,
"user": {
"id": 1,
"name": "another test",
"email": "another@testing.com",
"email_verified_at": null,
"status": 1,
"created_at": "2019-07-18 11:41:35",
"updated_at": "2019-07-18 11:41:35",
"deleted_at": null
}
}
]

I want the result to be something like that

[
  {
    user_id: 1,
    name: "test",
    bonuses: [
      {
        bonus_type_id: 1,
        amount: 100,
        is_paid: 0,
      },
      {
        bonus_type_id: 2,
        amount: 100,
        is_paid: 0,
      }
    ],
  },
  {
    user_id: 2,
    name: "another",
    bonuses: [
      {
        bonus_type_id: 2,
        amount: 100,
        is_paid: 1,
      },
    ]
  }
]
