How should i respond?

A jp book i really i wanted to read finally got translated in my mother language and i posted about my joy on one of my social.
Someone replied and asked if it got translated in English (my mother language isn't English).
I said idk bc i only knew the one I'm interested.
They then replied they found it in French.

I don't know what they want from? What are they asking. How should i reply? Good for you? Happy for you? Ok???

All options sounds like I'm mocking then... But i don't what to tell them...
