Template variables are not supported in alert queries, and notifications restricted

I was using an old grafana version, and I used notifications section with a telegram bot.
I just changed my monitoring vm, and set up again all my vm with grafana and prometheus.
On the old version of grafana, we could set limit for notification, with this screen…

And now, with the new version, we can not set manual limits, we only have this error…

How can i set alert for each panel, with grafana and telegram?
Thanks :slight_smile:
