Adding an external library/api pre build

I am using a WebGL build that has overlay features for the html. The button shown will call the javascript to make the overlay call.


Now when I press the button I get the error.



This is fine, because I have not included the line

<script crossorigin src="[URL='https://unpkg.com/@daily-co/daily-js%22>']" tabindex="-1">https://unpkg.com/@daily-co/daily-js"></script>[/URL]

within my html file that Unity exports. My question is, how can I have this bit included before I build out?

 

Thank you Jukka! I'll give it a read and come back with my results!

 

Thanks Jukka. That worked for me.
