Hi @happylemon ! Welcome to the Amplitude Community! 
Something I’ll like to add is that Amplitude Instrumentation Explorer is an extension in the Google Chrome Web Store that helps you examine and debug your Amplitude JS SDK instrumentation through interactions with your website: https://help.amplitude.com/hc/en-us/articles/360003032451-Instrumentation-Explorer-Debugger
If you aren’t seeing your events pop up in the extension, there are three reasons:
- You are not using Amplitude JS SDK
- You are not instrumenting Amplitude JS SDK correctly
- You are not doing an action that is trackable or set-up to be tracked in your instrumentation
Other than the three reasons above, there’s also adblocker which will block Amplitude tracking. But since you said you see events appearing when you are on the Amplitude website, I assume that you do not have adblocker on.
Hope this helps! Let us know if you have any questions.
