Chart object referencing vue-chartjs v4

vue-chartjs: "^4.0.7"

chartjs: "^3.7.1"

In v3 for vue-chartjs referencing chart component and using this.$refs.myChart._data._chart returns the chart object but after upgrading to v4 the reference no longer works as it's used to.

Any work around to achieve the same in v4?
