Thanks for your reply.
Oh, so it’s just using Python libraries to embed a Chromium browser? I know it’s likely a Chromium inside since when I playtest, the end result only matches what looks in Chrome and not in Firefox, though the default zoom is still different after weaved. (I know I can zoom in with Ctrl +, but I figured if I can make the user not need to do that at start that’d be nice quality-of-life)
If I am to treat it like any browser, then Javascript as I understand now will not be able to close the window. :(
