Changestream monitor all dbs not work using c# driver

hi

i use c# driver to monitor the changestream for all dbs except for system dbs, but not work, code as below:

    var pipeline = new EmptyPipelineDefinition<ChangeStreamDocument<BsonDocument>>().Match("{ $or: [ {operationType: 'replace' }, { operationType: 'insert' }, { operationType: 'update' }, { operationType: 'delete' }, { operationType: 'invalidate' } ] }");
    var options = resumeTokenStorage != null ? new ChangeStreamOptions { FullDocument = ChangeStreamFullDocumentOption.Default, ResumeAfter = resumeTokenStorage.resumetoken } : new ChangeStreamOptions { FullDocument = ChangeStreamFullDocumentOption.Default };
    using (var changeStream = await client.WatchAsync(pipeline, options)) {}

i create below mongo role and previledge

    use admin
    db.createRole(
       {
         role: "manageOpRole", 
         privileges: [
           { resource: { cluster: true }, actions: [ "killop", "inprog" ] },
           { resource: { db: "", collection: "" }, actions: [

                    "viewRole", 
                    "viewUser"
                ] }
         ],
         roles: []
       }
    )
    use admin
    db.grantRolesToUser("admin", ["manageOpRole"])

but when i start to monitor all dbs’ changestream, it report below exception:

Command aggregate failed: not authorized on admin to execute command { aggregate: 1, pipeline: [ { $changeStream: { allChangesForCluster: true } }, { $match: { $or: [ { operationType: “replace” }, { operationType: “insert” }

what should i do some setting for it? thanks.
