Custom social icon alignment

We created a custom Discord social media icon to use in this theme. Sized 50x50px, as per code info on the other icons. The alignment of the custom icon is to the top, whereas all others are centered horizontally and vertically. Any suggestions to have the custom icon on same levels as all others? https://mcanallys.ca/ on the right hand side of the footer Resize the browser to see how the icon aligns, depending on view.
