When a Hangouts conversation is deleted by one person, what happens to it for the others involved?

When a Hangouts conversation is deleted by one person, the conversation remains visible to the other participants until they choose to delete it themselves. This means that the action of one participant removing the conversation does not automatically affect the visibility of that conversation for others involved. Each participant retains control over their own view of the conversation and can delete it whenever they choose.

This feature allows for differing levels of interaction with conversations, where one person may decide to remove a thread without impacting the memory or access others may want to maintain. Consequently, the other options do not correctly represent the functionality of Hangouts.
