Credentials are saved for connect. Only Owner or admin can save them.
Owner or admin enters LinkedIn credentials on the sender so Connect can run later without retyping. Members can see senders. They cannot save the password or start Connect.
Workspace data stays in that workspace. Saving credentials is optional for the people who can connect. It is not a Member action. Privacy and the DPA cover the legal detail. Members never type a LinkedIn password in ReachyReach.
