[BUG] Cannot Open Plasmo + Next.js Chrome Extension App in Chrome Side Panel
What happened?
A bug happenedI'm currently developing a chrome extension using Plasmo, I actually created it from PlasmoHQ - with-sidepanel boilerplate.
However, the boilerplate is not opened in chrome side panel, like Copyleaks Chrome Extension. There is no any effects when I try to click the extension icon which is in the top right side of my Google Chrome.
And I'm also getting WebSocket connection errors when I inspect my chrome extension package.

Please take a look at package.json file here.
