The problem is they can’t justify your cost if you go outside the planned work load. They could probably still quantify it but it’s difficult to assess your impact when your effort doesn’t count towards velocity and delivery of business outcomes. If you work does impact those things, it should be a ticket/story/task so that the impact of work can be measured (seen…). I would suggest, in the future, adding these things to the backlog as you come up with them and bring them up during planning.
