Adding code to the header or footer of a lesson

Hi,
I am trying to use the Embed Code plug in to add some code (JSON structure) in the head of the lesson. This is the embed code plugin: https://www.ads-software.com/plugins/embed-code/

While I was able to add code to regular posts, the lesson’s html does not embed the codes. I tried multiple plug ins to add to the head of each lesson separately. None seem to work when it comes to lessons.

Will you considering adding a textbox with the lesson editor to allow inclusion of code in the head area of the generated html?

Or, can there be an update to allow the conventional head-code embed plugins (such as, Embed Code) to add code to the head/foot of the lesson html?

I appreciate any help on this.

Thank you!
