[BUG] Icon not working for devtools panel

[maybebansky]

What happened?

I'm creating a devtools panel. This is working however when I try to add an icon it doesn't show up.

I need the icon to be next to the panel name as it is for "Components" and "Profiler" here:

This is my devtools.tsx. Commented out are the different paths that Ive tried (Ive tried having the icon within the assets folder and also in the project root):

import projectHtml from "url:./panels/project/index.html"

// import panelIcon from "url:~/assets/icon16.png"
// import panelIcon from "./icon32.png"
// import panelIcon from "url:./assets/icon16.png"
// import panelIcon from "./assets/icon16.png"
// import panelIcon from "icon16.png"
import panelIcon from "./assets/icon32.png"

chrome.devtools.panels.create(
  "Test Project",
  panelIcon,
  // See: https://github.com/PlasmoHQ/plasmo/issues/106#issuecomment-1188539625
  projectHtml.split("/").pop()
)

function IndexDevtools() {
  return (
    <div>
    </div>
  )
}

export default IndexDevtools

I'm not seeing any errors in the terminal when I build the extension so unsure how to debug this.
