Hi,
This is the first time I'm making a pull request. Apologize if I'm doing anything wrong and I'll improve it.
Kindly please let me know how I can put a proper description and what else I'm missing in my PR.
We're trying to integrate ArgoCD with OpsGenie, however noticed priority was not able to be picked up by notification to send to OpsGenenie, so would expect the priority support can be added.
Thanks,
Patrick

Hey @patrick-tang , thank you for your contribution. Your change also covered in this PR https://github.com/argoproj/notifications-engine/pull/339/files . I think it will be better just merge last one because it covers all fields. For sure PR that you did is amazing and i am sorry that i didnt review it earlier, i just didnt notice it.
