Setting up Whatsapp Credentials for a client

Is there a better way to set up credentials for Whatsapp (or other integrations) for a client then to talk them through it over Zoom?

My clients want to keep the n8n build on my side so I can manage and update it for them, but I’m jumping on zoom and talking people with tech fear through where to click to get the credentials set up.

Is this the most efficient way? I’m still new to n8n overall. Any insight or shared experience is helpful. thanks!
