How to check which PEs are available for users in DACS or DACS WS?

@dgstudio I saw that @Jirapongse had given some code on how to use the API in this thread - also citing the user guide here. I also saw this thread where @Jirapongse advises you may need to contact the DACS support team directly via MyRefinitiv to get a file of all exchange codes and PEs if it is available. Let us know how you get on. @Jirapongse can you add anything here?
