missing slovak language for multilingual keyboard

Hello,

i was very excited when with the new iOS 18 there was a possibility for a multilingual keyboard. After an update, I was very disappointed when there is no option to add Slovak as the second language, although I am able to add it separately. Is there any plan to add there the rest of the languages? I am very eager for this functionality, as I hate switching between two keyboards all day long :( on Android I could do this like 10 years back
