Currently, when using Tempo Timesheets as the time tracking provider, the worklog author is "Tempo Timesheets". This affects several scenarios, for example:

1. Using REST API to get the worklog author:

    rest/api/3/issue/<issue-key>/worklog/<worklogID>
   

   Response:

   ...
   "displayName": "Tempo Timesheets"
   ...
   

1. Using Automation 4 Jira to send email to initiator when work is logged:
   Initiator is always resolved as "Tempo Timesheets" as well

It's possible to use the Tempo API:

• get Tempo Worklog Id by Jira Worklog Id (https://api.tempo.io/4/worklogs/jira-to-tempo)
• Get Tempo Worklog by its Id https://api.tempo.io/4/worklogs/ {id}

However, this approach has limitations, as for example "worklog_deleted" events can't be processed. It would be beneficial to retrieve the actual worklog author instead of the Tempo Timesheets account which is acting on behalf of the user.
