Ability to change text size on IOS

I just updated discord mobile app on my iphone, and now the text is so much bigger and obnoxious. WHY isnt there an option to change text size on IOS yet? My friend has it on his Android, but IOS users would like this option too. I know I can change the text on my phone settings, but I dont want my text to be different on my entire phone. JUST on discord.
