How to hidden "Download link" checkbox and "Link" tab ?

1. How to hidden "Download link" checkbox in "Insert Link" dialog ?
   I don't want to allow anyone to add download links. This could allow users to create download links that potentially contain malicious programs.
   

2. How to hidden "Link" tab in "Insert image" dialog ?

Manipulating the DOM by javascript:

const editor = SUNEDITOR.create((document.getElementById('sample') || 'sample'),{
    // ...
});

editor.onload = function (e) {
    // Remove the Link tab from the Insert Image dialog box
    Array.from(document.querySelectorAll('[data-tab-link="url"]')).forEach(element => element.remove());
    // Remove the Link content area from the Insert Image dialog box
    Array.from(document.getElementsByClassName('_se_tab_content_url')).forEach((item)=>{item.remove()});
    // Remove all "Download Link" checkboxes
    Array.from(document.getElementsByClassName('_se_anchor_download')).forEach(element => element.parentNode && element.parentNode.remove());
};
