Can't Add Emoji Plugin on CkEditor

RainLoop version, browser, OS: Rainloop v1.14.0

Expected behavior and actual behavior: Add Emoji button to CKEditor at Send Mails form.

Steps to reproduce the problem: 1) Downloaded the plugin: https://ckeditor.com/docs/ckeditor4/latest/features/emoji.html 2) Extracted the plugin in: rainloop\v\1.14.0\static\ckeditor\plugins 3) Edited the file: rainloop\v\1.14.0\static\ckeditor\config.js:

...
config.toolbarGroups = [
        { name: 'document',    groups: [ 'mode', 'document', 'doctools' ] },
        { name: 'clipboard',   groups: [ 'clipboard', 'undo' ] },
        { name: 'editing',     groups: [ 'find', 'selection', 'spellchecker' ] },
        { name: 'forms' },
        { name: 'basicstyles', groups: [ 'basicstyles', 'cleanup', 'emoji' ] },
        { name: 'paragraph',   groups: [ 'list', 'indent', 'blocks', 'align', 'bidi' ] },
        { name: 'links' },
        { name: 'insert' },
        { name: 'styles' },
        { name: 'colors' },
        { name: 'tools' },
        { name: 'others' },
        { name: 'about' }
    ];
...
config.removeDialogTabs = 'link:advanced';

config.extraPlugins = 'about,autocomplete,clipboard,dialog,emoji,link';
};

4) Edited the file: rainloop\v\1.14.0\static\ckeditor\build-config.js:

plugins : {
        'about' : 1,
        'autocomplete': 1,
