Until now, this feature was available to onlyWhatsAppusers on Apple iOS and desktop.
This new pause button will be visible to the users when they swipe up after pressing the record button.
The same button will be used to unpause and resume the recording.
It is also available after installing the new WhatsApp Business beta for Android 2.22.6.7 update.
Stay tuned for more updates!
