Hello, PR,
In order for Font Awesome 5+ to work in the menu, you need to copy not only the icon name but also its style as shown in the screenshot https://prnt.sc/BlEwuds_HwUy
We have done this so that the same icon can have different styles as shown in the screenshots below https://prnt.sc/DVDZ3Xd5WMEd https://prnt.sc/BlEwuds_HwUy https://prnt.sc/JqfCZSuxifrd
You can also use animation for icons simply by adding classes as indicated in the screenshot https://prnt.sc/-w7Yy6QMCoiB
Example – https://prnt.sc/K2N8lpyl2ul2 > https://prnt.sc/N-k51-RPPpm8
