YouTube widget missing from Learning Interactions

I recently upgraded from Captivate 9 to Captivate 11 (Captivate 2019, v 11.5.4.613). The YouTube widget is missing from Learning Interactions (and this widget is essential to my projects). I have the same issue whether I download the application onto a MacBook Pro (running Mac OS 10.14.6) or a PC (running Windows 10).

I see all the other Learning Interactions, but no YouTube. When I look on my MacBook hard drive (in Documents > My Adobe Captivate Projects > Adobe > eLearning Assets > Interactions_11_5), I see the .wdgt files for all the other widgets, but no YouTube.wdgt file).

Does anyone have any ideas how I can get this widget?
