Ring Alarm 🚨 IOS CRITICAL SOUND

Please can you investigate having a way to choose sound for any critical alerts From Ring Alarm - I had a critical alert go off at my parents at night , it was just by chance I was awake and the sound it emitted was just a little blip sound, had I been asleep it would have failed waking me up… this to me is a major flaw… I have checked settings and their is no way to change sound, yet on camera alerts I can choose sounds… please fix this urgently
