It solved the issue :) but one thing ( not sure about its complexity) :

The VisualLastReadMessageId is updated after navigating to the conversation for the second time but it also takes a short period to update. This makes the group uncollapsed for the second time too because it caught the initial value of the last read message Id.

I think it should not follow the last read message Id but what that id follows in the first place. From first check, seen in Message can be a good candidate but I am not sure.

Originally, it should be conversation.lastReadMessage, but need to check if it covers system messages

UPD: yes, it covers
