Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified

Hi,
The package works perfectly on Android versions before API 31, while mentioned exception is thrown for Android devices with API 31+, I managed to workaround the exception by changing the PendingIntent from FLAG_UPDATE_CURRENT To FLAG_MUTABLE
The exception with SmsSender
Before
val deliveredPendingIntent = PendingIntent.getBroadcast(
context,
UUID.randomUUID().hashCode(),
deliveredIntent,
PendingIntent.FLAG_UPDATE_CURRENT

After
val deliveredPendingIntent = PendingIntent.getBroadcast(
context,
UUID.randomUUID().hashCode(),
deliveredIntent,
PendingIntent.FLAG_IMMUTABLE

Best Regards
