How can I use custom editor?

[ladislavbili]

So I've used this webpage https://ckeditor.com/ckeditor-5/online-builder/ to generate editor with my preferences. Downloaded the zip file and my question is, how do I use it in react? Example for html works just fine but not in react.
Directly import from build folder into ofc crashed as it was too large. So I tried different approaches.
Last one that looks like it should work was to install it as a module using npm. So I installed it and it went just fine. Its in node modules as "ckeditor5-custom-build", package.json, "ckeditor5-custom-build": "file:src/components/ckeditor5" webpage loads just fine but when i try to import it in any way it doesn't work.
import CKEditor from 'ckeditor5-custom-build';
also tried
import {ClassicEditor} from 'ckeditor5-custom-build';
All I get is Module not found: Can't resolve 'ckeditor5-custom-build' in. How can I use this?

I also tried just directly using it, installing all of the dependencies creating the file linked below in my project but problem is, the dependencies don't even load, with message that one of the modules was not able to import css from the other module, but when I looked it was there. Still I think the first approach I tried should somehow work, I have no idea how though.

Here is the code of generated component so you can imagine what libraries I used.

Hi! Please, make sure that you import the compiled file which is in build directory of your package. The following import should work:

import ClassicEditor from 'ckeditor5-custom-build/build/ckeditor';
