[How to use ScrambleText in Vue]

I am trying to follow the examples as mentioned in this article: https://blog.usejournal.com/vue-js-gsap-animations-26fc6b1c3c5a

 

But I am having issues with it kindly help.

 

 

 

export default {
mounted() {
const { lawn2019 } = this.$refs
// eslint-disable-next-line
const timeline2 = new TweenMax()
timeline2.to(lawn2019, 3, {scrambleText: "anytext"})
},
