Filtering grid with LazyDataProxy


I saw that the Grid have filter inside of header, but when I use LazyDataProxy and try filter inside the header, I can’t filter, has any way to do this?

My goal is when we digit something inside the filter, the software will send a request to backend and return data with the filter, my software works very well in suite 5, but in suite 8 I can’t find a way to do this.

Unfortunately the add , remove , copy , move , update , changeId , sort and filter functionalities are not available in the lazy loading mode:
