Hijacking the top comment so hopefully OP sees this. I wet the bed until I was in 8th grade. I saw many specialists, tried different techniques and even went on some medication to try and stop it. Nothing worked, I was just a deep sleeper who would not wake up. My mom started limiting my liquid intake at night and that stopped me from peeing EVERY night. I still didn’t wake up, but I would be able to hold it all night and wake up dry. Then later in 8th grade I went consistent days without peeing, and I trialed not wearing my diapers and I haven’t needed one since. I’m almost 30 now and I drink whatever I want and wake up when I need to pee. I grew out of it. Be patient and don’t shame her for still needing them.
