How do I turn off closed captions running from the course start in Captivate 13.1?

I am working with a client, and we are building multiple modules. They are fairly happy with things, but they are not a fan of the closed captions auto-running as soon as the learner enters the course.

Toggling closed captions off from the TOC removes the option from the playbar, and toggling them off from publish disables them.

I found a Java Script workaround, but it only seems to work in Microsoft Edge (but no other browsers). Does anyone have a solution for this, or do we know if Adobe is working to fix this? I’m all for accessibility, but I also need to make my client happy.
