Embedding Videos from YouTube

Currently I'm working on a project that requires me to embed videos from YouTube.

However, while embedding them, I've figured out configuring the auto play and mute settings on the video, but I'm not able to turn off the captions automatically.

I have tried using the 'cc_load_policy = 0' but it's still not turning off the captions. Not sure whether it's me or YouTube.

Any support is appreciated!

This link says you could try setting it to 3 instead but the accepted solution claims that it is not possible

Yeah I've read that discussion but that solution isn't working too. I think it may be dependent based on the videos (user's settings perhaps) because I don't see this problem with every other video I've tried.
