Gnome Email Notifications
Formerly Gmail Message Tray
Utilizes Gnome Online Accounts to login to Gmail/Outlook and check your incoming email
Install gnome-shell version 3.22 or later.
Sign in with your Google and/or Microsoft account in Gnome Online Accounts settings.
Either install from https://extensions.gnome.org/extension/1230/gmail-message-tray/ OR run
git clone --depth 1 https://github.com/shumingch/gnome-email-notifications ~/.local/share/gnome-shell/extensions/GmailMessageTray@shuming0207.gmail.com
If you are getting any errors after logging in and out of gnome, try rebooting or signing back in to Google.
If you are getting "Forbidden Error 403" when attempting to view Gmail, you probably are not logged into that Gmail account on your default browser.
