Developer

• I am the original author or an authorized maintainer of this plugin.
• I have complied with all license requirements for the libraries used, including providing appropriate notices where necessary.

Plugin Functionality

• I have tested the plugin on both the Stable and Beta SteamOS update channels.
• My plugin is unique, or provides additional or alternative functionality to plugins already on the store.

Community Contribution

• I have added links to those feedback comments in this PR.

Millennium.callServerMethod is deprecated, and should be replaced with callable.

Other than that, the code seems fine. I'll just need a third party to test your plugin and leave a review here.

I can likely assign @madmaxgrey and he'll more than likely leave a review when he's available. We can wait for his response
