Using memory profiler on local WebGL build? Does it work?

I've got a WebGL build that I want to profile memory usage for. I've managed to create a development build and autoconnect to profiler. Both memory profilers I've tried don't work. I'm referring to the in-built memory section of the Unity Profiler, as well as the additional dediated memory profiler you can download through the package manager.

After selecting "capture snapshot" on either profiler, it just runs and perpetually tries to take a snapshot of the game running in my chrome browser. I've even left it on overnight and it was still running.

TLDR: Is there any way to profile memory usage on a local WebGL build?
