Happy (day of the week) greeting in email

hi

I’d like to set up a dynamic content fiend that updates to the day of the week so i can insert it into emails, like this:

happy Monday… (if email goes out on a monday)
or happy Tuesday (if the email goes out on a tuesday)

I set up a dynamic content field with this code:

<p style="box-sizing: border-box;">Happy <span id="today" style="box-sizing: border-box;">Tuesday</span>!</p>
<script style="box-sizing: border-box;">
	document.getElementById("today").innerHTML = new Date().toLocaleDateString('en-us',
	{
		weekday: "long",
	});

</script>

and it seems to be working, the field is updating, but how do I now insert this dynamic content field (which shows as ID 1) into my template email?

what token do I use?

thank you.
