How to initialize Grafana oncall to the specified organization

What went wrong?

What happened:

Grafana oncall only be initialized to Main org by default with API call below: curl -X POST 'http://admin:admin@localhost:3000/api/plugins/grafana-oncall-app/settings' -H "Content-Type: application/json" -d '{"enabled":true, "jsonData":{"stackId":5, "orgId":100, "onCallApiUrl":"http://engine:8080/", "grafanaUrl":"http://grafana:3000/"}}'

curl -X POST 'http://admin:admin@localhost:3000/api/plugins/grafana-oncall-app/resources/plugin/install'

Orgs other than Main org will prompt out "Unauthorized/Forbidden while accessing OnCall engine: /api/internal/v1/plugin/v2/status, status code: 403, check token" or "jsonData.stackId is not set", and there's no token created under Service Account section.

What did you expect to happen: I know the Grafana OnCall engine only support one instance of the Grafana OnCall plugin at a time.

I wish to not use the API call to initialize the oncall, so that I can configure it through the GUI in the org I want OR If I have to use an API call to initialize, I hope I can add the orgId option to the command

How do we reproduce it?

Install grafana oncall plugin through DashBoard CRD.
Enable oncall plugin in GUI.
Make API calls to install as suggested in [https://github.com/grafana/oncall/issues/4960#issuecomment-2335048517]
Config OnCall API URL: http://oncall-engine:8080/, click Connect.
Only Main org will connected successfully, other orgs will prompt out like "jsonData.stackId is not set" or "Unauthorized/Forbidden while accessing OnCall engine: /api/internal/v1/plugin/v2/status, status code: 403, check token"

Let me know if I'm wrong, I beliew the expected procedure is something like: We don't use API call to initialize, we install oncall in the org we want, token created automatically, we provide oncall-engine url, then everything should be done?
