How to connect several charts on chart load?

I am trying to develop a plugin for Grafana and I need to connect the charts. I cannot modify the source code so I need to add echart.connect on load of the charts?

I saw #9 and would like to know how can I do this?

Something like below,

```
const onChartReadyCallback = e => {
chart = useRef(e)
chart.group='abc'
echart.connect('abc')
}

```

other panel,
```

```
