No option to give separate font size for desktop & Mobile?

Hello Devs,

I’ve been trying to migrate my elementor website to block editor and found your plugin makes the process easy.

While reconstructing the page, I found that the font size is becoming same for both desktop and mobile. I do found icons for desktop, mobile, and tablet inside the typography section but, giving different values for different devices is not working.

Am I missing something or is it a bug?
