How to pass user/me avatar props to navbar? Next Js

I’m currently using Next Auth for my app’s authentication system. However, I need to pass user/me avatar object into the navbar. App.js doesn’t support getserversideprop so getinitialprop is the only option. Will using getinitialprop in app.js slow down the site as it disables auto static generation? Also, can getinitialprops even fetch data from user/me end point with bearer jwt token in the header?
