Someone probably knows the answer. Ask around. This should include either customers or customer advocates. If nobody knows the answer, then do the simplest thing that accomplishes what you need in order to proceed. Sometimes that means doing nothing. If there are multiple ways to accomplish what you need, do the one that leaves you in a more flexible state for future changes. You can bring up your choices or decisions to team members if you need, possibly during a standup or just ad-hoc.
If you aren't empowered to take one of those steps, then you are in a dysfunctional environment, in that case, collect your salary and keep your head down, and if you are so inclined, try to find a new company or team to join.
This piece was written by a highly-regarded scifi author a year and a half ago. I say that not to complain about the age but rather to marvel at the authors ability to describe so well something that is only becoming clear to many a year and half later.
