Help with grouping alerts and receiver requests

[AndreFCRosendo]

I'm trying to send a message to a webhook with all the alerts for a specific group.
Currently i am sending several messages one for each matcher and I don't know what I am doing wrong.
I expect to have only a single receiver request per "group_by" but I don't know how to do it and can't find a single example on the internet.
Any help is highly appreciated.

My most current configuration is as follow (sends 2 messages to the receiver):

route:
  routes:
    - group_wait: 1m
      group_interval: 10m
      repeat_interval: 1d
      group_by: [teams]
      receiver: "webhook"
      matchers:
        - teams="SRE"
        - cluster=kubernetes
      routes:
        # all alerts except memory
        - matchers:
          # java problem for certain aplications when reporting memory
          - alertname!=memory
        # memory alert except java apps
        - matchers:
          - type!=java
          - alertname=memory
