Shortcode with Meta Box Template

I can not get the shortcode to work with this add-on. I am trying to use the example on the the add-on page substituting prefix_ for provider_. If I use this add on do I have to register the meta box? I can get the shortcode to work with the builder.

I have tried

[rwmb_meta provider_title="provider_title"][/rwmb_meta]
[rwmb_meta meta_key="provider_title"][/rwmb_meta]

and a variety of other combinations, not sure what I am doing wrong.
