Local Notification not showing when game is killed in some android devices in Unity

I’m using the Mobile Notifications Unity Package for local notifications, but I’m facing an issue: I’m not receiving local notifications on most devices when the game is killed, even if their Android version is 13 or higher. Can anyone please suggest which package I should use to get local notifications even when the game is killed? I’d also like to mention that I don’t want to use Firebase. I want local notification for both android and IOS.
