Image Rendering for Email

I am running on Grafana 9.5.3. I have Grafana to send latency alerts to my email, but I want an image of a time series graph to be sent. I had it with an older version that I did not set up. I’m trying to set it up now that we updated grafana. Using Ubuntu, I installed Grafana CLI using the command given:
grafana-cli plugins install grafana-image-renderer
and followed all the steps with no luck. I havent been able to get it to work. The email still works but no image.

Did you set up a docker container with the correct image and configure the specific configurations in the grafana.ini file?
