Google App is updated automatically in your Google Chrome
browser. But if you want to update it manually, do the following:
Open Google Chrome on your computer.
In the address bar, type chrome://extensions. Alternatively, you may go to the hamburger icon (three horizontal lines) on the top-right > Settings. Now click Extensions on the left sidebar.
At the top of the extensions page, check Developer mode. This is next to the big Extensions text right at the top.
Click Update extensions now under Developer mode.
