Get workflow output from custom form element custom code

I need to get application data set in another workflow in a custom form element to process some data for inserting an interactive chart in a form. 

I can run the workflow, but can't seem to get the workflow output. The results are all undefined and logged before the workflow is run.

> const result = await messageService.commands.workflow.run.execute(workflowArgs).then(result => console.log('Result from inside await',result));

          console.log('WORKFLOW RESPONSE FROM GET APP DATA', result);
