How can I redirect submissions to whatsapp or telegram account?

I'm sorry, but we do not have this feature. 

A workaround would be to configure Click to Chat feature with Whatsapp (https://faq.whatsapp.com/en/android/26000030/?category=5245251). You can have the Whatsapp URL in the Thank You URL settings, so people are automatically redirected and prompt to send you the message on Whatsapp when submitting the form.
