Help 🥲

I’m almost a little embarrassed to post this here because you all have such thriving plants but here she is. We moved a few years ago and this is the best lit spot we could find but she’s just not thriving. Leaves continue to grow on the top and there are a few small ones coming in at the bottom but the middle of the plant is just completely bare now. I’ve never pruned it, so maybe that’s something that needs to be done? Would love any advice!
