Text on slider image on everypage

Hello,

I would like to add text on top of the slider image and for it to show on every single page not only on the homepage.

Just like in the demo:
https://www.templateexpress.com/adam/

This is the site:
https://www.studiomyla.com/

I basically would like the Studio Myla Europe to be centered in the slider image and to show on all pages/blog pages of the site.

Could you help?

Thank you!
