I've had my ZZ plant for about eight months now and I'm still figuring out the watering schedule

I've had my ZZ plant for about eight months now and I'm still figuring out the watering schedule. Mine's in a bright indirect spot and I keep second-guessing myself—the soil dries out pretty slowly, which I know is normal for *Zamioculcas zamiifolia*, but I worry I'm underwatering it. The leaflets look healthy and glossy though, so maybe I'm overthinking? Does anyone else struggle with this, or am I just being paranoid? I'd love to hear how often you water yours.
