How to add Social signin buttons on Registration page?

I'm trying to add social sign in buttons on Registration page as well, similar to the Sign in popup

I want to do this without an extra plugin.

I tried adding the following code in /applications/dashboard/views/entry/registerbasic.php

<?php if (!defined('APPLICATION')) exit();
$Methods = $this->data('Methods', []);
$SelectedMethod = $this->data('SelectedMethod', []);
$CssClass = count($Methods) > 0 ? ' MultipleEntryMethods' : ' SingleEntryMethod';


// Render the buttons to select other methods of signing in.
if (count($Methods) > 0) {
    echo '<div class="Methods">'
        .wrap('<b>'.t('Or you can...').'</b>', 'div');


    foreach ($Methods as $Key => $Method) {
        $CssClass = 'Method Method_'.$Key;
        echo '<div class="'.$CssClass.'">',
        $Method['SignInHtml'],
        '</div>';
    }


    echo '</div>';
}

But this didn't help. Kindly let me know the correct way to do so.

I'm using Vanilla 3.3 and the default plugins Facebook Social connect 1.2.0 (Todd Bury) and Google Signin 1.1.0 (Official)
