How to activate the new security feature launched by Watsab

According to Forbes magazine, a few days ago Watsab launched a new security feature that prevents people who can access your device from spying your messages in Watasab.
The activation of the new security feature requires the installation of the latest version of the application Wattasab (2.19.20).

If the update of the application on your device occurs automatically, you can confirm the latest version by pressing Settings and then "Help". You will find the latest version of WatSab as an image at the top of the screen.

After making sure that the version of Wattab is newer and has the number (2.19.20), press "Settings" again, then "Account", then "Privacy".
At this point you will see "Screen Lock" and you will have two options on the screen: Touch ID or Face ID, depending on which version of your smartphone you are using.

Once you have enabled one of the two options, you can choose when to close the application. Here you will have 4 options to close: one minute, one minute later, 15 minutes or an hour later.
