When adding multiple Alertmanager configs in the plugin, messages are posted to a random channel about mattermost-plugin-alertmanager

Good afternoon. I also encountered similar behavior of the plugin. I don't have an alertmanager cluster, only 1 copy. I created 3 channels in one team. And I get something completely different

route:
  receiver: 'telegram_bot'
  group_by: ['alertname']
  group_wait: 5s
  group_interval: 1m
  repeat_interval: 12h
  routes:
  - match:
      alertgroup: 'SD'
    receiver: 'mm-home-sd'
  - match:
      alertgroup: 'InfraRules'
    receiver: 'mm-home-infra'
  - match:
      alertgroup: 'Hardware'
    receiver: 'mm-home-hardware'

thanks for the report, are you willing to open a PR to fix this issue?

We don't have the environment to build Go applications without a lot of effort. So dry-analyzing the source code was as much as I could do at the moment

After figuring out that Mattermost supports most of the schema from Slack, we have now switched over to using the Slack configuration from Alertmanager. We've lost time calculations (using a timezone other than UTC or calculating durations, I've opened prometheus/alertmanager#3762 for that) but gained extensive customizability.
There are a lot of Slack template examples on the net to have a solid starting point for this.
Thanks for this Plugin, we would have loved to stick with it but in the current state we needed a solution that we can easily develop ourselves.
