Add example where icon can be added by function

[IlyaBerzhanin]

Hi, I had a task to add custom icon to the toast, so tried to find the example in docs, but didn't succeed.
Here is the example from docs:

But if after setting "iconPack: 'callback'; " we can use prop "icon" as function which returns us HTMLelement:

So it is not an issue, maybe some kind of recommendation to add such an example to docs as it was not obvious for me and I suppose some people can also get stuck for a while.

Thanks a lot!

@IlyaBerzhanin Could you please share the code snippet with plugin initialization and usage?

The following seems to work for me:
Initialization:

Vue.use(Toasted, { iconPack: 'custom-class' });

Usage:

this.$toasted.info('This is a info alert—check it out!', {
      duration: 0,
      icon: 'my-info-icon',
});
