elementOrSelector - Give it either a valid CSS selector or an HTMLElement instance directly
calLink - Cal Link that you want to embed e.g. john. Just give the username. No need to give the full URL https://cal.com/john. It makes it easy to configure the calendar host once and use as many links you want with just usernames

Actions
You can listen to an action that occurs in embedded cal link as follows. You can think of them as DOM events. We are avoiding the term "events" to not confuse it with Cal Events.
1
<script>
2
Cal("on", {
3
  action: "ANY_ACTION_NAME",
4
  callback: (e)=>{
5
    // `data` is properties for the event.
6
    // `type` is the name of the action(You can also call it type of the action.) This would be same as "ANY_ACTION_NAME" except when ANY_ACTION_NAME="*" which listens to all the events.
7
    // `namespace` tells you the Cal namespace for which the event is fired/
8
    const {data, type, namespace} = e.detail;
9
  }

})
