Can't access "Environments to share" values in steps started by "Bitrise Start Build" step

For the Bitrise Start Build step in bitrise io there appears to be a way to pass through environment variables however I can’t seem to figure out a way to access the variables in the steps that have been started.

There doesn’t seem to be any documentation on what (or at least any I can find) on how to access these set env value in the started steps with the workflow editor.

I have got this working now.

In in the “Bitrise Start Build” step I set the “Environments to share” value to ENV_VALUE and added a “Set environment variable” step before the “Bitrise Start Build” step. I added the correct destination key (in this case: ENV_VALUE) and a suitable value.
