I’m trying to embed some 3rd party javascript code inside of my LiveView page from Vesselfinder:

<script type="text/javascript">
    // Map appearance
    var width="100%";         // width in pixels or percentage
    var height="300";         // height in pixels
    var names=true;           // always show ship names (defaults to false)
    // Single ship tracking
    var imo="9506291";        // display latest position (by IMO, overrides MMSI)
    var show_track=true;      // display track line (last 24 hours)
</script>
<script type="text/javascript" src="https://www.vesselfinder.com/aismap.js"></script>

If I just include this in my show.html.heex, this will not work as I have to refresh the page to make the embedded map visible (i.e., if I navigate directly to a page that should show the embedded map, it will show up but if I navigate from another LiveView to the page that’s supposed to show the embedded map, there is no map at all).

As Elixir is the first language I have learned, I have no experience with javascript, but I feel there should be something possible here with the Phoenix Liveview JS Hooks. Is there somebody that can point me in the right direction?
