Listen for extension icon click

[maxpatiiuk]

When user click on our extension in the list of extensions some action should happen.

Could possibly switch to the calendar tab, or open a new page by adding code like this to the Background/index.ts file:

chrome.action.onClicked.addListener(function () {
  chrome.tabs.create({ url: './src/public/background.html' });
});

FYI, before action event can be intercept, we need to register the action in the manifest:
