我有一个会话管理器单例类。在它里面，我存储了一个身份验证令牌。当应用程序崩溃或进程死亡时，身份验证令牌（活动数据）销毁。如何处理它？

@Singleton
class SessionManager
@Inject
constructor(
    private val sessionRepository: SessionRepository,
    private val cacheManager: CacheManager
) {

    private val sessionScope = CoroutineScope(Main)

    private val _sessionState = MutableLiveData<Resource<AuthToken>>()
    val sessionState: LiveData<Resource<AuthToken>>
        get() = _sessionState

}
