These actions are only applied to Cloud edition, for Server/DC edition ProScheduler integrates natively with Jira Worklogs, you just need to log time in Jira and it is synced to ProScheduler

Open the ProScheduler timelog panel

Click on Add Timelog to log time

If you replaced Jira builtin Time tracking provider by ProScheduler then you can log time using the Timelog tab in issue details screen
