Hello @Lillinator, I extend my gratitude for your response. When I test your suggestion, members of the group will be able to observe all posts. In fact, my goal here is for the topic to be visible only to the individual who created it. Other users should not be privy to the topics created by other users and should refrain from engaging in any interaction.
For instance; User A has created a significant topic in the Bug Report category for reporting an issue. This topic should not be visible to Users B, C, or D in the same forum. Only User A who created the topic, alongside moderators and administrators, should be able to view the topic opened by User A.
