Showing Details in Sidebar from List View

Hi all,

I'm hoping to implement a custom click handler from a Freedom UI list view that opens a preconfigured sidebar that displays a detailed view of the record that was clicked. I've successfully been able to capture the click event, open the side panel, & fetch the Id of the active row, but have not been able to figure out how to use that data to actually display on the sidebar; it's always popping up blank. Has anyone here tried to do something similar?

Here's my current code for reference:

{
				request: "crt.HandleViewModelAttributeChangeRequest",
				handler: async (request, next) => {
					let sidebarCode = "";
					let rowId = "";
      				if (request.attributeName == "GridDetail_9lgj3r0_ActiveRow") {
						rowId = await request.$context.GridDetail_9lgj3r0_ActiveRow;
						sidebarCode = "LeadSidebar";
					}


					if (sidebarCode != "") {
						const handlerChain = sdk.HandlerChainService.instance;
						await handlerChain.process({
						    type: "crt.OpenSidebarRequest",
						    sidebarCode: sidebarCode,
						    $context: request.$context,
							modelInitConfigs: [{
								action: "edit",
								recordId: rowId
							}]
						});
					}
					
					return next?.handle(request);
				}
