Viewing here means the member hasn't talked in the last week, and "viewed" the messages in the group. Translating word by word doesn't work here, so we need to reveal the hidden meaning. The other translation "预览成员” is wrong btw, he probably thought it was "to view the members".

The original translation only stated that they are viewing members, but did not explain what to get view. This is likely to cause confusion for users in Chinese. The new translation supplements the viewing content, making it easier to understand.
