"Item not found" error is returned when i try to get file details that has been shared by the external user

Question

Shared with me API provides me the list of all files and folders that are shared by internal and external users. The Shared API URL is mentioned below https://docs.microsoft.com/en-us/graph/api/drive-sharedwithme?view=graph-rest-1.0&tabs=http

But when I try to access the shared DriveItem resource of the file that has been shared by the external user bypassing DriveID and File ID into the API /drives/{remoteItem-driveId}/items/{remoteItem-id} The API throws an error as -

{
"error": {
"code": "itemNotFound",
"message": "Item not found",
"innerError": {
"date": "2020-10-20T12:07:39",
"request-id": "5a3b3836-fe3e-450a-837e-1b3e962ac94b",
"client-request-id": "5a3b3836-fe3e-450a-837e-1b3e962ac94b"
}
}
}

But the Same API works fine with the file shared with Internal Users. Am I missing something here any help is greatly appreciated?

For external tenants make sure you append ?allowexternal=true according to the public document and then give a try.
