getPerm<T extends FrappeDocument> method

@override Future<RequestResponse<List<DocPerm>>> getPerm<T extends FrappeDocument>({ required String? doctype, T? document, })

Returns the list permission of the current user of a certain doctype.

Optionally can specify the permission of a certain document (TBD).
