How to automatically add captions/subtitles in FCP iPad?

Hi everyone, I’m trying to figure out how to automatically create subtitles on my project in Final Cut Pro for iPad

I can find a guy to do this on the Mac version however there seems to be no indication of whether this is possible on the iPad. I presume for a monthly subscription this would be possible.

Am I missing something? If anybody has any tips please let me know because if this is impossible, I’ll find a different app to edit my content.
