I have this statement that should project and return a list of attachments as follows :

 var mappedAttachments = recordAction
     .PPAttachments
     .Select(async x => new AttachmentRequestModel()
     {
         AttachmentId = 1,
         AttachmentContent = await GetReportAttachContentAsync(1),
         AttachmentName = "name",
         AttachmentType = "1"
     })
     .ToList();

This statement return a List<Task<AttachmentRequestModel>> how can I change it to return List<AttachmentRequestModel> instead?
