Can you give some more details about the problem?
Technically this should work out of the box. Example with "USA Zip Codes": https://zurich.maps.arcgis.com/home/item.html?id=dc123f738bf846779c49db6472f82a4b
You can open them in SceneView and MapView and the points show with 41k features (https://services.arcgis.com/P3ePLMYs2RVChkJx/arcgis/rest/services/USA_ZIP_Code_Points_analysis/FeatureServer/0/query?f=json&returnIdsOnly=true&returnCountOnly=true&spatialRel=esriSpatialRelIntersects&where=1%3D1)

Hello @SS12 ,

This just looks like a simple service max request configuration on your server endpoint. By default 2000 is the limit of max features you can return on a query to a service published to ArcGIS Online. The following is a knowledge article on how you can update this to a larger number:
https://support.esri.com/en/technical-article/000012383

If you have an ArcGIS Enterprise setup the workflow would be to go to Server Manager and update the properties on the service.

Thanks,

Jose
