Need help using groupable to resize with vue3

## Environments
* Framework name: Vue
* Framework version: 3
* Moveable Component : groupable

## Description
Hello, I want to use groupable to resize multiple elements but can't find a proper example to use with vue. Examples for react or vanilla js use the "events" variable, which is undefined when i try with vue3. So what do i have to use to resize a group properly ? 

Thanks :)
