I was trying to run an APK on Android Studio Mac and inspect that on Edge/Chrome using the below method.
edge://inspect/#devices
But edge/Crhome doesn't show me the "Inspect" button with other details
I'm using a Mac M1 Android studio latest version. both Edge and Chrome up to date.

By default chrome/edge dev tools will show your app on the list when app is open on the screen that contains WebView (It will allow inspection of that WebView).
EDIT: WebView debug is enabled by default on simulators, on a real device you need to enable this explicitly (Thanks Robert( https://developer.chrome.com/docs/devtools/remote-debugging/webviews/#configure_webviews_for_debugging
Personally, I'm using stetho library which allows inspecting apps using chrome dev tools, It has really nice options. http://facebook.github.io/stetho/
