How to launch Hangouts Chrome extension via AppleScript?

I am trying to launch a Google Chrome extension in AppleScript or Terminal. By "launch," I mean replicate the act of clicking on the extension icon found in Chrome's toolbar. The Chrome extension in question is Google Hangouts. Clicking on the extension icon creates a new pseudo-window in Chrome that houses the Hangouts dialer. ---------- Here is what I've considered: - I uncovered the physical location of this extension on my hard drive: - /Users/Me/Library/Application Support/Google/Chrome/Default/Extensions/ nckgahadagoaajjgafhacjanaoiihapd/2018.123.418.2_0 - However, I didn't find anything of significance. - I entered chrome-extension://nckgahadagoaajjgafhacjanaoiihapd/ in Chrome's address bar, which led to a *"Your file was not found"* message. - I do not know of a way to associate a keyboard-shortcut with the Hangouts extension. The Options item in the context menu of the Hangouts extension is not selectable (i.e., it is greyed out). - The Hangouts extension has a second shortcut, found in the systemwide, top menu bar. I tried programmatically clicking on the menu-bar icon with code like this (source) : - tell application "System Events" to tell process "SystemUIServer" to tell (menu bar item 1 of menu bar 1) to click - But, I am unable to get AppleScript to click on any icon that falls to the left of the wifi symbol. - I am aware that Hangouts has a web interface (https://hangouts.google.com) . However, any phone number that is given to the web interface is dialed by the extension (not by the web interface itself). So, interacting with the extension directly is more ideal. ---------- Is the dreaded *mouse-click simulation* the only way to accomplish what I want? ----------
