What is what does initialchatfriendslist mean?

Initialchatfriendslist is a term that refers to a feature on Facebook that shows the user an ordered list of their most frequent chat partners. This feature is often mistaken as a list of people who have visited or viewed the user's profile regularly, but this is not true. The list is generated by an algorithm that takes into account the user's interaction with other users, such as messaging, commenting, tagging, or reacting to their posts. The list may contain friends, family members, colleagues, or people the user has interacted with frequently on Facebook. However, the order of the list is constantly changing based on the user's activity on the platform. Therefore, it should not be seen as a definitive list of the user's closest friends or top followers.
