CKEditor: remove link type parameter, but set URL as default link type?

I am using the Link plugin for CKEditor, and I am trying to remove the Link Type parameter so that the user can enter the address in the URL field and not set the Link Type parameter. When I use the code below, it removes the Link Type parameter, but when I try to click the link that it creates, it does not open the link as intended.

So, I am wondering how can I set the “Link Type” by default as a URL so that the link can be opened successfully, but also remove the “Link Type” parameter manually?

CKEDITOR.on('dialogDefinition', function (ev) {
    var dialogName = ev.data.name;
    var dialogDefinition = ev.data.definition;

    if (dialogName == 'link') {
        var infoTab = dialogDefinition.getContents('info');
        infoTab.remove('linkType'); 
    }
});
