Create Author Info Inline Under Title Of Pages

Hi,

I'd like to create an author info area just under the page title of pages (excluding homepage/contact etc) I think this can be done in elements.

I'd like something very simple. An author avatar, the name and when the page was last updated. I don't want a link for the author name to the author pages, rather to just keep it as text.

This is an example of how I'd like it to look https://www.sorceesourcing.com/paying-manufacturers-vietnam with the only thing I'd add is to also add a last updated date to the inline section.

Here's a screenshot of the example https://paste.pics/DTR7L

Do you know how I can create this author area similar to the example?

Thank you in advance!
