Seeking Tools to Find Top LinkedIn Posts by Keyword

Slightly off-topic but I know that there are many LinkedIn experts in this community so would love to get your thoughts on this: I would love to be able to do research on best-performing LinkedIn posts on specific topics. For example, I would love to search for "ProductHunt" and see which posts have performed the best on the keyword. I was considering the following tools: 1. Phantombuster: Does not have a Phantom for scraping for a keyword, just for posts from specific people. 2. Scraping the LinkedIn Post search results -> did not find an easy-to-use tool as InstantDataScraper and the Clay extension are not supported on LinkedIn. 3. Kleo: While I love the Chrome extension as I can easily search for top-performing posts of specific people, it does not seem to have a feature to search & save generally well-performing posts. Do you have any other ideas that work well for finding posts on specific keywords? Thanks a lot!
