You can pair with someone, or have informal chats, or plan some online game with your colleagues, have presentations in your team around work or non-work related things, setup a book club.

EDIT: sorry, I am re-reading this and please be assured my intent is not to say you're "wrong", but just to offer some minor remediation ideas that might be helpful.
