I’m on a Pro plan (for my personal account) and Enterprise plan (for my work account) and need to import a manifest file specifically in the web app, and not desktop app. On the desktop app, I am able to see Plugins > Development > Import from manifest. However when I go to the web app, under Plugins I can’t see “Development”. When I go to the actions menu and type “import from manifest” nothing shows up in the web app (though it does in the desktop app).

How can I import a plugin on the web app?
