Topic: Script development / Need help with Gmail Addons script error

Sorry to bump the post, but I was not sure where to post this.

Thanks for the great script. I'm trying to add Google Docs as an addon, and it works, except for the fact that it auto loads to Google Docs, as soon as I load the Gmail inbox. Why is it doing this? I copied the script for Google Calendar and modified it a bit to open Google Docs. here is what I have inserted:

});
GmailAddons.registerAddon(
{
id: 'tdGDocs',
name: 'Google Documents',
url: 'https://docs.google.com/?tab=mo#not-in-folders',
indicatorLabel: 'Documents'
});

What have I done wrong, and is there a way to ad Google Docs as an addon? Thanks!
