Android Question WhatsApp Library don't check if WhatsApp Business is installed

[asales]

I tried to use the "isInstalled" method of this library from @MarcoRome :
https://www.b4x.com/android/forum/threads/whatsapp-library.51571/
with WhatsApp Busines, but don't works.

How I can check is the WhatsApp Business is installed?

Thanks in advance for any tips.

The packagename of Whatsapp Business is: com.whatsapp.w4b

Thanks!
I made this function:

Sub W4bIsInstalled As Boolean
   Dim ret As Boolean = False
   Dim in As Intent
   Dim pm As PackageManager
   in = pm.GetApplicationIntent("com.whatsapp.w4b")
   If in.IsInitialized Then
       ret = True
   End If
   Return ret
End Sub
