WG Discussion:

Hi @diksha1999
In today's WG call, we delved into the issue of preflight option support. The consensus reached was that the provision of preflight option support is a broad requirement. Therefore, if the UI sends a request to the EventListener, then there should be some proxy server like nginx or some other server to handle inflight request before reaching the EL
