Hi,
I think it's useful for users to select from a list their own notifications sound. The list must contain at least 3 sounds.
The actual sound is not the best choise. Here are some reasonable ones:
https://notificationsounds.com/message-tones/graceful-285
https://notificationsounds.com/message-tones/all-eyes-on-me-465
https://notificationsounds.com/notification-sounds/you-wouldnt-believe-510 /*i use this*/
You can find better, i'm sure.
Thank you.
