How to Find the Latest LinkedIn Access Date for Users Using Clay?

Hi everyone, Does anyone know how to find out the latest access date for each user on LinkedIn? Among the prospects I've found using Clay, I want to identify who is active on LinkedIn. I'm aware of some methods for checking information such as each user's LinkedIn posts, shares, comments, or overall engagement. However, I'd like to know if there are other ways, and since I don't use external services, I want to find a solution solely within Clay.
