How to add missing fullcalendar features

Hi
i would like to know if it’s possible to add more features to the calendar based on fullcalendar docs.
I would like for example to have the hours slots in week and day view,
The fullcalendar website say:

A TimeGrid view displays one-or-more horizontal days as well as an axis of time, usually midnight to midnight, on the vertical axis. The two predefined TimeGrid views are the **timeGridWeek** and **timeGridDay** views. They can be initialized in an [ES6 setup](https://fullcalendar.io/docs/initialize-es6) like so:

```
import { Calendar } from '@fullcalendar/core';
import timeGridPlugin from '@fullcalendar/timegrid';
...
let calendar = new Calendar(calendarEl, {
  plugins: [ timeGridPlugin ],
  initialView: 'timeGridWeek'
});
...
```

Or you can choose to initialized the TimeGrid views [as a global bundle](https://fullcalendar.io/docs/initialize-globals):

```
<link href='fullcalendar/main.css' rel='stylesheet' />
<script src='fullcalendar/main.js'></script>
<script>
...
var calendar = new FullCalendar.Calendar(calendarEl, {
  initialView: 'timeGridWeek'
});
...
</script>
```

How can I do that in wappler?
Do I need to create a custom javascript file?
What I would like is to add missing featuresin wappler from fullcalendar documentation.
The last version of full calendar is 5.6.0 but the one in wappler is 4.4.2. It is possible to update?

Thanks
