Go to Setting, you can select either the built-in browser or Chrome browser in WtsToolkit.
Built-in browser
The built-in browser defaults to Microsoft Edge, and by selecting this option, you can log in to multiple WhatsApp accounts. For more details on creating multiple WhatsApp accounts, please visit Multi Accounts Features Page.
Chrome
If you opt to use Chrome, you will be working in Google Chrome, and the multi-account feature in WtsToolkit will not be available.
