How to turn on sound captions in Minecraft Bedrock?

I play on Minecraft Bedrock Edition, and for my own convenience, I wanted to turn on sound captions so I could play on low volume while not missing any important information. I looked it up, and it said that the option to turn it on should be in either "Music and Sounds" or "Accessibility", but I couldn’t seem to find it in either.

Are sound captions simply non-existent in this edition, or is there some way I can turn them on? I know for a fact that it is in Java, but I can’t seem to find any info on if it is in Bedrock. I’d like to note that I want to be able to turn them on completely vanilla, no mods or clients.
