Fontawesome fonts are not showing on Illustrator

I tried to work on the iPad instead of the desktop, but the Illustrator apps show icon fonts were missing. I spent a few hours finding out the solution, but there was no way to add custom fonts such as Fontawesome icon fonts. Please help me to find out how to do it.

If it is not available now, when should I expect it?

Just like the Creative Cloud's "Add fonts" of the desktop version
