It's not just you. Both our phones do it and I think Android Police posted about it as well. Let's hope a system update addresses it "soon".
If you have time, can you try an app that lets you choose what mic to use and see if it's present with a certain mic here, too? https://play.google.com/store/apps/details?id=com.splendapps.voicerec
Edit: got time and tried it. I can't replicate the popping with any of the different mic sources with this app. But Snapchat still does it. I'm going to "Send Feedback" within my device settings and pray someone pays attention to it.
I can't answer your Rode question but on my Samsung I've used Voice Recorder Pro. You can probably get by also with the voice recorder that comes with your phone (Samsung comes with one - no idea about the Pixel phones).
[UPDATE] Okay I think I solved the issue. My guess was some app runs a background process that prompts the microphone so I've uninstalled Voice recorder by Splend Apps and the issue seems to be gone
Niech ktoś mi poleci jakiś dobry dyktafon, bez reklam, bez żadnych płatnych opcji, bez logowania itd. Bo się zdziwiłem jak mój telefon nie miał dyktafonu zainstalowanego. ~~Kalendarz już se skombinowałem, bo ten od Googla wymaga zalogowania się, więc fuck this shit.~~
Using speakerphone switches what mic is being used. You most likely didn’t damage the actual mic with the sim tool as they are offset from the hole.
In the settings of this app, you can directly choose the different mics/recording method to test the hardware.
This page has diagrams of all Pixels and their microphone locations.

I'll probably show more or less options depending on the device and hardware support.
This app can do that.

Someone else posted it on this subreddit that they used to test it out. This is the app: https://play.google.com/store/apps/details?id=com.splendapps.voicerec
