Wordpress and Schema Markup

Hi guys. I'm pretty new to the SEO field. I mean I was social media for the longest time. Now I made my own site on WordPress and I'm trying to add schema markup.. its not working on the "text" side of the tabs on the page editor. I see that I need to go into the .php files etc... how do you do this? and does it work for every theme?

(also I'm no coder lol)

Thanks!

I'm not exactly sure what you mean, could you give a little more info?

Actually, what you want? I am really confused with your question. Please share a simple screenshot.

well, if u are no coder and want to add schema-markup then I would use google search god damn... 2nd search result would be a plugin... /plugins/all-in-one-schemaorg-rich-snippets/ on wordpress-page
