layout files in magento 2.3

I created default.xml for my module.

When i made some modification in this file using “before.body.start” this works fine.

But if i try made any modification to “header” or “top” i can’t i tried different names like: “header.panel”,

“header”,

“hader.cointainer”,

“top”

…. with no effect.

<referenceBlock name=”amgeoipredirect\\\\\\\\\\\\\\\_popup” remove=”true” /> – WORKS

<referenceContainer name=”after.body.start”> – WORKS

<referenceContainer name=”after.page.wrapper.start”> – HAS NO EFFECT

I want prepend my block to <header>, how to do this?
