Insert search in custom header

Hi! I try to make custom header and want to insert my header after the main header like this However I didn’t found how can I reuse the search from the default header, can it be pasted as widget and how to do this? Or this is impossible

Not quite sure what you are asking for, but in any case take a look at this?:

I mean to paste this search in my custom header
