The compatibilist view is that there is no contradiction between free will and determinism, because free will refers to macro states and determinism refers to micro states.
In addition, in the many-worlds view of quantum mechanics, we don’t follow just a single sequence of events, but all physically possible sequences of events, where the points where sequences branch off each other can correspond to different decisions we “freely” took. Meaning, when we make a decision, all applicable options of choice will become actual reality.
Compatibilism is a fancy way of saying "free will so much does not exist that what determists call free will isn't even a valid definition to use as a starting point for investigating an answer." It's not an answer to the question, it's a denial of it.
Another, simpler interpretation of Compatibilism is "if free will doesn't exist, then believing it exists or not has 0 effect on anything, because our beliefs are predetermined, and so at human scales the answers Yes and No are equivalent in all observable ways".
