The FetchVersions method is a static method of the Sandbox.Package class. It asynchronously retrieves a list of revisions for a specified package identified by the identString. This method is useful for obtaining different versions of a package, which can be helpful for version control or rollback purposes.
To use the FetchVersions method, you need to provide the unique identifier of the package as a string and a CancellationToken to handle task cancellation if needed. The method returns a task that, when awaited, provides a list of revisions for the specified package.

Console.WriteLine($"Revision: {revision}");
