Business Purchase Mobile Menu how to have center text aligned? How to add icons?

Hello, I’m trying to replicate the ‘Business’ demo linked here https://www.wpmobilemenu.com/demos/ (second down). I’m having a difficult time simply placing my menu links as ‘text-aligned: center’. They are showing as in a horizontal line with no proper spacing. Does this require custom css?

Also, I’m having a difficult time finding where to place icons on top of each menu link (shown in the demo). Please let me know where this is located or if additional css is required. Thank you! Much appreciate.
