Is it possible to add an icon into the message of a toast error or do I need to install a different/another module? I'm using vue and trying to add a component as an icon at the moment but not having any luck.
this.$toast.error('<icon-paperclip />')
Here it's written that you can pass either String or HTML.
String
HTML
Since a Vue component is a bit more than that, you will probably not be able to pass it directly.
Meanwhile, you could probably look for some HTML icon and inline it here.
