Recommended Launch Point for Pulling out Multiple Leads' Activity Logs

Hi Community,

I've been looking for  launch point for pulling out MULTIPLE leads' activity logs AT ONCE.

I understand it's possible to export the data for each lead but it takes tons of time!
Hopefully I want to use some exciting service such as launch point.

Does anybody know some information to achieve this?

p.s. I found the article related to this:

Thanks!
