WhatsApp Embedded Signup is Meta's own sign-up window that Meta partners use to connect businesses to the WhatsApp Business Platform. In it you log in with Facebook, pick or create your business portfolio and WhatsApp Business Account, enter and verify your phone number and set a display name. In Lead Pattern it opens from the Home dashboard.
In Lead Pattern
Connecting through Embedded Signup in 4 steps

Sign in with Facebook and select or create your business portfolio and WhatsApp Business Account.
