scrum board - total estimates in backlog

[Pablo]

Hi

I have o question - maybe it is  sth you have managed before

I have a Scrum Board (in the matter of fact huge massive of them) and everything works perfectly but I don't know how turn on estimates total in my Backlog. (the same as you can find in active and future sprints - nothing tricky)

I found this: https://jira.atlassian.com/browse/JSWSERVER-13591

but - ehh almost 4 years

maybe anyone knows some workaround/dark feature/plugin
