@kittaakos, I'm having trouble reproducing this issue. I'm on MacOS 12.4, Chrome 102. What browser are you using?

Thank you for your time checking it.

I used Brave (Version 1.40.105 Chromium: 103.0.5060.53 (Official Build) (x86_64)) on macOS 12.3.1, but I can confirm that it works with Chrome (Version 103.0.5060.53 (Official Build) (x86_64)).

#11217 already exists for the electron part, and the browser part is invalid. I am closing this issue.
