Can‘t add firend

Hello,

I have troubles adding a friend. I‘m running Minecraft v. 1.18.2. on iPad and when I find a person who I would like to add as a friend, there is no button to add a friend. There is a choice between „friend“ and „favourite“, but no matter what I choose, threre is no „ok“ button and after choosing „friend“ or „favourite“ I have to press „x“ аat the top right to close the window (please find the attached screenshot). And then, when I closed the window, I see that I still have no friends. Could you please help me to solve this issue?
thank you in advance.
