Is it possible in the site builder to just add, say, a video component on its own? I can’t find it in the list

Anybody know if Jetboost & Finsweet work together better? When I tried previously I found it to be a bit buggy but I notice they are working in sync on the new Relume Resources page? I would do without Jetboost but it seems to be the smartest solve for favoriting (and thus everything else you can do with that functionality). Any knowledge on this topic much appreciated. Thanks
