Hi, when you guys update sdk for 'UnreadMessageCount'?

// Detailed description of issue.
whenever we receive message from user in groupchannel, it count and refresh repeatedly.
Please fix this issue, it looks 4 month ago, has issue with it? or Just open Unity SDK source on github. then at least we can fix it issue by our self.

// If problem, please fill out the below. If question, please delete.
[SDK Version]
// What version of the SDK are you using?

[Reproduction Steps]
// Create ‘GruopChannel’
// Join channel users at least 2,
// Send message from A to B, then B will had ‘UnreadMessageCount’ as 1 always.

// Everytime

Also, why ‘OnReadReceiptUpdated’ events callback always called? everytime user received message
