I removed the "PollSCM" from the "triggers" section of my declarative Jenkinsfile. And then I enabled "Scan multibranch pipeline triggers" and the "Periodically if not otherwise run" option. This method of polling seems to work fine so far. I'm afraid I will need to rely on polling because our git repo is on another machine in a different facility. Our jenkins is deployed on an EC2 host and the company doesn't want to open a port to the world for the trigger notification.
