SyntaxError: Unexpected token =

[Artur-Fedjukevits]

Hi.

Trying to add this module to OpenHab. When trying to run example code, I get SyntaxError:
`2023-01-21 21:50:01.476 [INFO ] [org.openhab.core.model.script.myexec] - results /etc/openhab/automation/js/node_modules/sectoralarm/lib/client.js:13
snooze = ms => new Promise(resolve => setTimeout(resolve, ms));

npm v9.3.1
Node v18.13.0
Ubuntu 20.04.5

What could it be?
