Setting Up Multi-Agent Workflows with Lindy: Key Considerations

Hi, I want to set up a multi-agent workflow where I have a number of GPT agents that can work individually, but also their output from one GPT can be passed to the next GPT. I want to create this for our customers, so am I correct in thinking that our customers will need to have their own Lindy accounts so I can set up these agents for them? Would they be able to set up a free Lindy account and for me to simply send the links to these agents to run? If they have my shared links, will they be able to see exactly how those agents have been built and the prompting instructions? I would like to remain confidential. If so how else could I do this using Lindy?
