The request for 1:1 calling Chrome support is still “on the backlog”.
1:1 calling works in Edge.
Group calling and meetings works for Edge & Chrome.
I hope to have more information to share soon.

I tried just loading Teams in Chromium (Version 66.0.3359.181) on Linux just now and got an unsupported browser error.
We’re pleased to announce the Teams client for Linux is now available for preview. Please see details at https://techcommunity.microsoft.com/t5/Microsoft-Teams-Blog/Microsoft-Teams-is-now-available-on-Linux/ba-p/1056267.
