ArgoCD notification on Google Chat

[PhamQuang-512]

i have following this documentation about setting template to send notify to google chat https://argo-cd.readthedocs.io/en/stable/operator-manual/notifications/services/googlechat/
But I can only send simple messages, not card messages. When checking the logs of the argocd notification server, it shows "time="2024-04-13T04:55:55Z" level=info msg="Trigger test-google-chat result: [{[0].y7b5sbwa2Q329JYH755peeq-fBs 2024-04- 13T04:52:36Z [test-google-chat] true}]" resource=argo-cd/service-platform-uat-user-setting-public"
Here is my template:

I have the same issue, did you find a solution to this ? I also could only send the title with the first widget, but the moment I write the second widget from repository to author, it throws me errors.

Apparently we can send JSONs but there is no example in the doc ...
