Suggestions for the function of images_upload_handler

[tanggd]

now，use:

// eg:
const example_image_upload_handler = (blobInfo, progress) => {
    if (myCondition) {
        reject({
            message: 'Image format does not meet the requirements',
            remove: true,
        });
    }
};

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  images_upload_handler: example_image_upload_handler
});

1. I hope to add a parameter named 'timeout'. The notification automatically closes after the value set in the timeout property elapses in milliseconds.

// eg:
const example_image_upload_handler = (blobInfo, progress) => {
    if (myCondition) {
        reject({
            message: 'Image format does not meet the requirements',
            remove: true,
            timeout: 5000,
        });
    }
};

2. When parameter 'message' is set to false, I want to customize the notification instead of using the default one. I only need the 'remove' parameter.

// eg:
const example_image_upload_handler = (blobInfo, progress) => {
    if (myCondition) {
        reject({
            message: false,
            remove: true,
        });
    }
};
