Hi Dana

Hope you are doing well. As described, you want to add a button to the PDF form to allow people to attach files.

Please look at the correct answer marked in a similar discussion https://community.adobe.com/t5/acrobat/add-an-quot-attach-file-quot-button-to-a-pdf-form/td-p/8812972?page=1 and see if that works for you.
