We are interested with tracking the app installations (global and per profile) for security reasons.

The following Atlassian Cloud pages currently provide access to this information, but there's no endpoint to retrieve them through REST API:

Admin:
https://admin.atlassian.com/s/<org_id>/user-connected-apps

Jira:
https://<site_name>.atlassian.net/plugins/servlet/upm

Confluence:
