Setting up Closed Captioning/Zoom Support/Bolt

I want to set up Closed captioning.  The instructions state to set up  a third party app and then go into details of programming the application.

But as I've found out every time using help here, the info is out of date and incomplete.  Where do I find a list of these services?  Do I have to pay?  Can I trust them?  Do I install them?

That's a big gap.  And simple questions such as, "Where is a list of 3rd party transcription services" in any form gets "I don't understand your question.  I've gone to tools to help me to re-write my questions at 2nd grade level.  But Bolt does not understand.  I've gone down to 3 word questions.  Bolt understands nothing!

And when it doesn't understand, there's link to reach a real human.  When you do, it won't go on until you open another application and pull up a number.  That number is hidden and requires you open another help article to find it.  But then there's no real reason to place that information in the request.   It's a wild goose chase to just reach anyone.

There's no way in the world that anyone has ever tested out Bolt and declared it to be good for consumption.  I can't find any reason for having it other than to prevent customers from finding answers and make them keep searching on their own and not burden Zoom with responding to questions.  But I would love to be proved wrong.

So, are there simple, up to date instructions for closed captioning that are up to date and include all of the necessary information including the services?
