WhatsApp is introducing a new feature that provides more control to group chat admins (under beta testing). This feature allows group chat admins to decide who can join their group chat by requiring approval for new members.
The new approval system will require new members to be approved by the group chat admin before being allowed to participate in the group chat. If approval is not given, the new member will not be able to join the group chat. Admins will have the ability to enable this feature on a per-group basis, so they don’t have to enable it for all group chats.

A new option called “Pending participants” will also become available for each group chat that has enabled the approval feature. This option will allow admins to see a list of everyone who has requested to join the group chat and choose whether to approve or deny their request.
WABetaInfo, an online platform that specializes in WhatsApp news, has reported that this feature is being rolled out to beta testers and is expected to be available to more users in the coming days. This feature will be available to those who have the latest beta version of WhatsApp downloaded from the TestFlight app or have downloaded the latest stable release of the app from the App Store.
The ability to control who can join a group chat is an important feature for admins, especially in cases where groups are used for specific purposes or are private in nature. This new feature will give admins the ability to approve new members and maintain the integrity of their group chat.
