Been playing around with a new install of Solus and Ive linked my Google account via the Online Accounts feature. I can view all my drive files just fine, but I cannot open any google docs files successfully. I get the following error:

There is no application installed for "application/vnd.google-apps.document type" files

According to Gnome, since the 3.18 release Files should open Google Doc files in the default webbrowser.

From https://www.omgubuntu.co.uk/2015/09/gnome-3-18-google-drive-nautilus-support :

For Google-specific files, or files which no native app has support, GNOME will helpfully open it in a web browser.

There are relevant YouTube videos demonstrating this feature successfully.
