Should I message recruiter on LinkedIn?

Hi everyone. I applies for a SWE role (tech company in SEA) via Kalibbr. I see that my applications has been moved by the recruiter to "in review". It has been a week since then. My current observations are:
1. The job posting is ending in a few weeks... but it's hidden. I suppose they have reached max number of applicants. But it's not closed yet. You just can't find it in the search/ browse feature.
2. HR hasn't done anything with my application other than put it "in review". They have looked at my resume and profile... But haven't really accepted or declined for the next phase.

Should I message the recruiter on LinkedIn to ask the status of my application? It shows me the recruiter's name who reviewed my application. Would messaging them seem creepy?

Thanks!
