How can I start reffing ECNL games

I am from CT and I want to start reffing ECNL games I believe I have enough experience to ref games but I don’t know how can I start reffing ECNL. I look at the CT assignors website and I can’t find any for ECNL and when I go to ECNL’s website I try to find games but I can’t find any for CT. Does anyone know how to start reffing ECNL games in CT?
