In the 'description' of this automated work item is the email address of the person assigned to the task. This doesnt really do us any good so I'm trying to automate a way to extract this information and select this person as the 'Assignee' drop down box under the 'Details' section. I havent had much luck and I'm looking for some help here.

Things Ive tried:
I tried creating a variable to extract the Email
@{{issue.description.match("Engineer/Supervisor/Drafter: ([A-Za-z0-9:;_. -/&#]+).*@)}}
and then assign the work item to that smart variable
{{extractedEmail}}
I also tried to do an advanced branch to extract the employee ID from that email
{{lookupIssues.extractedEmail.accountId.distinct}}
and then assign the work item to that smart variable
{{employeeID}}
