Do i need to upload fallback fonts if i use webfont/google fonts preinstalled in webflow?

Hi guys, I am using Google Fonts, which I downloaded from Google and uploaded to the project settings in Webflow. I am planning to start using Webflow’s system fonts (Web fonts/Google Fonts) that I see in the font dropdown menu in the style setting. If I use these, do I still need to add fallback fonts in the project settings?

thanks
