How to change the Chrome system page title by a Chrome extension?

Question

I want to change the tab like edge://extensions/ or extension setting page title to add a '*' at the end of the original title if get the selection context on any page after mouseup event.

I create a simple Chrome extension.

change.js

var title = document.title;
    document.addEventListener("selectionchange", function () {

        if (!window.getSelection().toString().trim()) {
            document.title = title;
        }
    });
    document.addEventListener('mouseup', function (e) {
        var text = window.getSelection().toString().trim();
        if(text) {
            document.title += '*';
        } else if (!text) {
            document.title = title;
        }
    });

The manifest.json file. It shows an error when I add it on the extension page.

Error: Invalid value for 'content_scripts[0].matches[0]': Invalid host wildcard.
