The element is a button with a link. That link can be anything. So just upload the resume in your server and then change the old url of the button with the new resume url. Check button’s settings for it.
I don’t follow “upload your resume in your server” I uploaded it to my media library, with a new name and then edited the link code on the about me page. this did not work.
You can upload a file or image from your wordpress or directly into the server using a ftp connection. It’s the same result.
Then edit the buttons url from it option panel in the wordpress admin panel.
I see the button is functional and send you to the pdf document. If that is not the right document, then you must have set the wrong url. Please know that this is not the element’s fault.
