Create header above primary menu

I have a wordpress theme installed and I have Thrive Architect installed , I used the Thrive landing page builder to build a header that contains some social media links and a button at the top of the primary menu that contains the logo and some pages.

That header is shown on the homepage and the other pages , But for example when I visit a post that header doesn’t exist , Only the primary menu header.

So I’m wondering how to show that header all over my website.

Should I create a child theme and edit the header ? Is there is a way for doing that without losing it on updating the theme ?
