Issue - Customer is firing our addCustomView function https://learn.microsoft.com/en-us/power-apps/developer/model-driven-apps/clientapi/reference/controls/addcustomview on Power Apps grid control - Power Apps | Microsoft Learn which is in preview feature. It is failing to recognize this function however same code does work for regular grids. We don't see this issue listed in known issues/limitations hence reporting it. Current implementation retrieves the lookup query using the fetch below, but Power Apps Grid does not work. The issue is that on Power App Grid (Event OnRecordEvent), the lookup column is not being set up based on the fetch.
