How to use plasmo with a side panel?

I was previously using the tabs folder workaround, but it seems that @lab has added proper support for a sidepanel.tsx file (awesome work Louis). I cannot for the life of me figure out how to get this to work even looking at the example. Is there something obvious I'm missing? https://github.com/PlasmoHQ/examples/tree/main/with-sidepanel

To add this was trying to manually achieve this off of using create plasmo and using pnpm create plasmo --with-sidepanel. For each when clicking the extension's icon I expect the side panel to open up and display sidepanel.tsx, but nothing happens. No errors are displayed with --verbose.

@gehrig. can you inpsect the output manifest.json and paste it here? (in the build/*-dev) I tested that on brave and chrome, worked doh

Odd. This what you're looking for? I did check and the sidepanel.html is being auto generated and referencing the right js file, too. This was with chrome.

i'm having the exact same problem did you get to solve it?

Hey folks, As far as I understood you want to open sidepanel on extension icon click. This is the official doc: https://developer.chrome.com/docs/extensions/reference/api/sidePanel Also, I've added following to my background script:

chrome.sidePanel
    .setPanelBehavior({ openPanelOnActionClick: true })
    .catch((error) => console.error(error));

Oh, and important point, you shouldn't have popup.html file, otherwise it won't work
