TCP connections in Chrome extensions... not possible?

Yeah... it won't work...

I'm an idiot...
Why didn't I look into this first....
I need to make a TCP socket connection...

I was working on the extension first...
And then, the moment I got to the TCP socket connection stage... I realized I was screwed.

There are a lot of things giving me a headache right now.
The first is something about Chrome apps and extensions ending support in 2022?
Wait, is that for real or what... Then why am I doing this... There are less than three months left ㅡㅡ..

And second, it looks like Chrome apps support TCP sockets...
But extensions? No way...

Anyway... even setting that aside, the important question is...

Is there no way to do this...? My plan to connect and use a scale and a barcode scanner from a Chrome extension is going up in smoke...
