Anime Subs

Hi! I'm trying to watch anime or random YouTube videos and while they have CCs, they are not embedded. I'm trying to find the subtitles for what I'm watching, but it's not really mainstream so there are no results when I search the subtitle searchbar.

Is there anyway we can use the CC of the video itself? Thanks!
