@Nishant_Jariwala Thanks.
But There have any another way to do from my custom App.
I know It’s Possible from customize form. but I need to do from my app.
You should do the changes via Customize Form only, it creates a Property Setter record in the backend. And then to make the changes as a part of your custom app, add “Property Setter” in hooks/fixture. And run bench --export-fixtures command to export the Property Setters.
