Why the social icons do not include Skype, WhatsApp, Viber etc?

I suppose you were able to get the Object installed correctly in the end since you have been able to check what services were installed?

I can confirm that the services you mention are in fact available in the Object, as you can see from my screenshot:

Try it out and let me know if you find it

Thank you
