If a component 'CompOne' has two slots, like this:
<slot name="headerSlot"></slot>
<slot name="mainSlot"></slot>
How can we, from App.vue, direct the text 'Animals are interesting!' into the slot 'mainSlot' in
'CompOne'?
<slot-comp @(15)>
Animals are interesting!
</slot-comp>
<slot-comp v-slot:mainSlot>
Animals are interesting!
</slot-comp>
<slot-comp #mainSlot>
Animals are interesting!
</slot-comp>
