Grafana Cloud integration with GitHub

Hello my name is Adilson. I’m trying to integrate Grafana Agent with GitHub. But I’m having trouble configuring agent-confi.yaml. can anybody help me?

Here is my code:

integrations:

    prometheus_remote_write:

      - url: <my prometheus api url>

    github_exporter:

      enabled: true

      repositories:

        - grafana/agent

        - grafana/grafana

      organizations:

        - prometheus-community

      users:

        - <my github username>

      api_token: <my github personal access token>

Where can I put my credentials like username and prometheus API key?
