How do I tell this gamer-girl "I love you"?

We met on apex when we just started the game (we both switched to pc from console at similar times) and we started using in-game chat to talk to each other. We then added each other on discord and hopped on a call, face revealed etc. She's the most beautiful women I have personally ever seen. I have built a good friendship with her and we frequently play together. She doesn't talk much bc she told me 'she doesn't like the sound of her voice'... Does it mean she's not into me orrr? Anyway, any tips on how i should break the news or approach her would really help!

PS. If this helps, she is a bit older than me, not by a lot though.

PPS. She's German, I'm Polish
