Merge a collection using the same key values

I have two collections with data to combine:

//1
  [
     [
       "date" => "2019-02-15",
       "clicks" => 1,
     ],
   ]
//2
[
     [
       "date" => "2019-02-15",
       "users" => 1,
     ],
   ]

it is necessary that the collection elements (arrays) that have the same values ​​for a particular key are combined

<?php

$c1 = collect([
    [
        "date" => "2019-02-15",
        "clicks" => 1,
    ],
    [
        "date" => "2019-02-16",
        "clicks" => 3,
    ],
]);

$c2 = collect([
    [
        "date" => "2019-02-15",
        "users" => 4,
    ],
    [
        "date" => "2019-02-16",
        "users" => 5,
    ],
]);

$c1->merge($c2)
    ->groupBy('date')
    ->map(function ($items) {
        return Arr::collapse($items);
    });

$collectionOne = new Collection(['foo']);

$collectionTwo = new Collection(['bar']);

$collection = $collectionOne->merge($collectionTwo);
