Embed transcription data not working?

Hello,

When I select a file in my project I can go to the transcribe window and transcribe the file without having to put it on a timeline.

But nothing happens. I get all the windows and options and can even click start.

This makes it look like it could transcribe files not in the timeline and add the converted text to the metadata of the file.

Is it possible to do this? I thought it was possible in the past, but as the language I needed wasn't supported back then I never really looked in to it other than some tests.
