@CrabNejonas just add devtools to an app that has the updater setup or set it up on the example (sucks, tauri doesn't work well on workspaces for the allowlist stuff)

[johann-crabnebula]

I think with the latest changes the updater spans should show up without any extra code. I will be closing this one for now. Please let me know if you still need this @lucasfernog-crabnebula

(Still keeping the branch around)
