Fullcalendar Vue slot templates

Fullcalendar docs mention only one slot template, "event-content" that can be used to inject Vue via slots. There are also others like day-header-content or day-cell-content, they aren't mentioned anywhere to handle scoped slots, but they are mentioned when docs mention content injection. With that in mind I tried to use cell-content(referenced here: https://fullcalendar.io/docs/resourceAreaColumns) from resource timeline feature, but it doesn't work. Are there any scoped slots for premium features? I would expect it to work like with every other content injection(referenced here: https://fullcalendar.io/docs/vue#slot-templates)

So while this works:

<FullCalendar>
    <template #eventContent>
        <p>Example</p>
    </template>
</FullCalendar>

This doesn't:

<FullCalendar>
    <template #cellContent>
        <p>Example</p>
    </template>
</FullCalendar>
