I tried this locally and it seems if you create a new button “Call microflow button” and then create a new microflow it will automatically set two parameters in your microflow
If your microflow is already created, just simply add another Order parameter and that should work fine.
But since you're working in a data view and 1 object of the list view it won't give you the entire list.
Maybe use a retrieve where you retrieve all the past orders? This way you still have all the old orders.
