I am currently working in a previous organization as a second line support engineer, and while I am working there, I update my regular activities and support details in ServiceNow, so you can ask me regarding that without any problems.
My relationship with ServiceNow is as a user who creates requests regarding issues such as machines not properly connected to the internet or printers not working, and I have access based on the support profile.
I use ServiceNow to investigate issues, update my findings, and fix the issue directly, or if any on-site intervention is required, I forward it to my next level or escalation. For day-to-day activities, such as rebooting servers, we want to get a change request approved before proceeding after business hours or on holidays, and we keep the ServiceNow ticket in my queue, updating our findings with screenshots and details before closing the tickets.
