Add affiliation of author as footnote on report

Question

I'm trying to add author affiliation as footnote following the following response on another question: https://tex.stackexchange.com/a/214425/252049

Following is what I have tried. I'm getting the affiliations next to the names, and not as footnotes. Would appreciate any help. Thanks!
