[Linux] TypeError: undefined is not an object (evaluating 'window.external.invoke')

Hi Juan,

I started working on a package manager GUI sometime last year and settled on webgui. I got pretty far into it but had to stop working on it due to other things taking higher priority. I have some time now and wanted to continue development but I'm getting stumped by this error I was not getting before.

I'm using Thomas's nim_nimble_gui example GUI app to showcase the problem. But basically, clicking any of the 'Nimble commands' buttons does not run their respective Nim backend function/logic. Instead, the console logs the following error: TypeError: undefined is not an object (evaluating 'window.external.invoke').

This used to work, as I remember playing with the example GUI apps. Trying the example app on macOS Big Sur works fine. I also installed Ubuntu 20.04 on a spare machine and got the same error.

Would you happen to have any insight as to what could be causing this error?

Which OS has the bug?,
Windows is kinda buggy, works for me on Arch and Bedrock.

The issue is happening on my machine running Ubuntu 20.04.

Could you ever get behind this issue? I am seeing the same error on Ubuntu 22.04.
