I noticed that there is an RMA state machine on the StateTransitionsManager object that seems to be used for RMAs. Does Litium support using a custom RMA state machine at this point? If so, I wonder if there are any docs describing the process.
Litium does not support custom state machines but you can configure the one that exists in platform, see the `RmaStateBuilderĀ“ in accelerator project.
For the state transition engine you can find documentations here.
