Anyone using LiveKit to make outbound calls?

Hello here. Nice meeting you guys I am new to automation. I've actually built a couple of workflows in n8n, but I've never got a real client yet. So all the credentials I used are mine and I have full access. So I'm thinking when I start to get clients, how do I set up their credentials (like Google for instance) when I don't have access to their google account. And some clients might have issues giving me their raw logins (username and password). So, is there a way I can set up Google credentials for a client when I don't have their raw logins? I would appreciate your responses.
