Best Approaches for Building an Agent on Lindy Client's Account

Hey everyone! 👋 I'm new to Lindy and I'm building an agent for my first Lindy client! I just wanted to ask what is the best approach here? Should the client create an account and invite me as a member to build the agent? Should I create an account on his behalf and use his credentials to work there? Would appreciate some general recommendations on best practices to work with clients!
