Easiest answer is the FBI only investigates. They don't prosecute. That is DOJ; Attorney General makes that decision, ultimately.
Problem with the FBI at this point is the corruption in their "investigations". Again, they don't prosecute; they provide information. But the information was intentionally biased, false, and corrupt in order to influence an election. When that failed, they continued with the corruption to try to unseat the elected President.
