The method GetRepositoryPullRequestsAsync is not working (C#)


I found a C# library GitHub - lvermeulen/Bitbucket.Cloud.Net: C# client for Atlassian Bitbucket Cloud
How to use GetRepositoryPullRequestsAsync(BitbucketWorkspaceID, RepoName)?

I have an AppPasswordAuthentication working.
But the call GetRepositoryPullRequestsAsync does not return any PR.

I need to find any merge that was done with specified branches(example: from any branch to develop branch) and specified time frame (example: one month time from now).
What method should I use?

Any help well be appreciated.
