unsecure due to theme java links in script

it is deemed unsafe even when installed as https.

but I found this in the code – which links directly to the theme as the culprit:

<script type=”text/javascript” src=”http://lendorphoglacour.com/wp-includes/js/wp-embed.min.js?ver=5.4.2″></script&gt;

not https and there are several of those.

so it seems my potential readers are denied access because of this.
