How to Find the Latest Date of a Person's LinkedIn Activities Efficiently in Clay

Hi everyone. I've been exploring Clay a lot lately, and I have a question: how can I find out the latest date of a person's activities on LinkedIn? I've tried some methods and obtained the person's activities, such as comments, likes, and so on. These activities include the date they were made, but it costs at least 10 credits. I'm looking for a more efficient way. Thank you in advance.
