How to Override Tax Details on Invoice Item via Rest API?

Hi,

I need to override the tax details when creating a new invoice but this is having no effect and the standard tax rate is being applied to the item.

Can anyone suggest a solution?

An example call is shown below.

I have set taxDetailsOverride = true and included the taxDetails section.

Also, taxDetailsReference:id = "NEW1" to reference item 1 (I saw this as a solution in different post)
