Implementing Toast component in Polaris theme with HTML

Store Design
1

How can I call Shopify Polaris toast js function with HTML/Jquery?
I have checked this https://polaris.shopify.com/components/feedback-indicators/toast
and found an example of HTML but there is no JS provided in this example.

Which function do I need to call to show a toast?
How can I pass props for the message, time delay and error boolean etc?

If you’re not using React, there’s no help from Shopify on any JS.

I’m using Svelte and going to try theme my toast like Polaris and see how that goes.
