markMessageAsDelivered not works as expected

[geolyth]

Describe the bug
When I sent a message in the chat to another user, also if the push notification is triggered, I do not see double tick in my chat.
I already added the related code (I'll add as comment to this issue).
Sometimes seems that opening and closing the chat double tick appears and sometimes the previous message seems to have double tick (but not the current one).

Also another question, what happens if the app is killed? Does it continue to work as expected (maybe not because seems relying on push notifications and to handle killed state we need to use notification payload in the Firebase notification)?

SDK version

• 6.30.0

To Reproduce
Steps to reproduce the behavior:

1. Send a message from account A
2. Push notification is received on smarpthone logged as account B
3. See a single tick (not double one)

Expected behavior
If markMessageAsDelivered is implemented I expect the same behaviour I see in this #5979

Device:

• Vendor and model: Any
• Android version: Any

onPushMessage = { pushMessage ->
                        // Mark the message as delivered when a push for a new message is received
                        if (EventType.MESSAGE_NEW == pushMessage.type) {
                            ChatClient.instance()
                                .markMessageAsDelivered(messageId = pushMessage.messageId)
                                .enqueue()
                        }
                        // Return false to let the SDK handle the push message and show a notification
                        false
                    },
