Azure work items related API is not returning Linked PR/Commit related detail.

I have created a couple of WorkItems

- I have linked Github Pull request and one commit with the first work Item.

- I have linked Azure Repo's Pull request and one commit with the second work Item.

I hit API to get workitems

https://dev.azure.com/{organization}/{project}/_apis/wit/workitems/{workitem_id}?$expand=relations&api-version=7.0

I am getting related(linked) Pull request(Pr No)/commit(only commit sha) as following. But I am not getting any clue like which is project/repository of this Pull request/commit. 

Is there any way to get these detail of Pull request or commit?

Note: Same is happening for even Azure Repos' commit/PullRequest
