Function insertIntoEditor Custom function to handle inserting the image. If you wanted to upload the image to a webserver rather than embedding with Base64, you could use this function.

Example function, uploading to a webserver:

insertIntoEditor: (imageBase64URL, imageBlob, editor) => {    
  const formData = new FormData();
  formData.append("file", imageBlob);

  fetch("/upload", {method: "POST", body: formData})
    .then(response => response.text())
    .then(result => {
      const range = editor.getSelection();
      editor.insertEmbed(range.index, "image", `${result}`, "user");
    })
    .catch(error => {
      console.error(error);
    });
}
