Slack has started offering a native app for Linux recently. It is still in beta but works pretty smooth and you can definitely install it to use Slack in Linux.
Slack provides Snap, DEB and RPM packages. If you use Ubuntu, you can install Slack from the Software Center itself.
It has all the features that you would expect from the native client, including desktop notification, auto-login and options to change teams etc.
If you don’t want to use Snap, there are binaries available for Ubuntu (.deb) and Fedora (.rpm) for 64 bit systems. You can download the binaries fro the Slack download page.
