EditorJS Setup Image Block with WordPress

I’m coding a blog site with WordPress and I want to use EditorJS as editor. I know there is a plugin for this, but I want to install this editor without plugins.
I can save the written content to the database now and I can edit the previously saved or shared articles, but I cannot add/upload images. How do I upload and use images from the EditorJS Image Block to WordPress?

PS: I found a library called "Plupload" but I don’t know how to use it.

I put the block I was talking about here.

    image: {
    class: ImageTool,
    config: {
      endpoints: {
        byFile: "http://localhost:8008/uploadFile", // Your backend file uploader endpoint
        byUrl: "http://localhost:8008/fetchUrl", // Your endpoint that provides uploading by Url
      },
    },
  },

thanks in advance
