I would like to be able to use the Azure DevOps API to send emails about certain pull requests.
I am looking at this page as a reference: https://docs.microsoft.com/en-us/rest/api/azure/devops/git/pull%20request%20share/share%20pull%20request?view=azure-devops-rest-6.0
I am not sure how the body of the POST should be formatted, especially the "IdentityRef" entry. How do I get this IdentityRef for individual users?
