Will this workflow close the existing open issues which do not have activity for more than 90 days? Looking at the issue queue, most of them do not have activity for 90 days, my concern is the workflow should not close them silently without us triaging first.

@gongmax The workflow will close only the ones that carry 'obsolete' label and to gain 'obsolete' label first it needs to get the 'stale' label. SO the short answer is NO.. No issues will be closed silently
