@all not working in grafana

I am sending alerts notifications from grafana to Google Hangouts Chat. Notifications working fine but I am not able to notify all the users in that room. I used @all but this is not working. For slack @channel is working fine.

Am I missing something?


Can anyone help please!

Hello @tafsiralam, I don’t have personal experience with setting this up, but have you tried using <users/all> as it is mentioned in Google Hangouts Chat docs?

Yes @ivanahuckova Already tried but It’s not working in Grafana. It’s working fine when I am sending a request using curl.
In short <users/all> working in curl but its not working in Grafana.
