Please follow the path below to set the featured image in the inner main title:
Appearance > Customize > Header Options > Header Image
There you can add images by clicking on Add new image
That’s not what I asked for. I don’t want the same image in all posts, pages and product headers.
I want that the Featured Image we select in the posts, pages and for products be the image we see inner-main-title, instead of seeing that Featured image as an individual image at the top of the post, page or product page.
