FantasiaDK/GetScreen.Me ? reverse-engineered prompt

Build me a simple WordPress plugin for GetScreen.me that lets clients start a remote support session from my site.

I want an admin settings page where I can enter my GetScreen.me API key, and then a shortcode I can drop into any page or post to show a support form or button. When a visitor submits it, the plugin should handle the connection flow with GetScreen.me so the client can initiate the session easily.

Please make it feel clean and straightforward, since this is meant to be easy to set up for non technical users. If possible, also support automatically submitting the form when a name is passed in the page URL using gsm_name, so I can prefill the client name and move them straight into the flow.

Keep it compatible with recent WordPress versions, and make sure the plugin includes the usual activation, uninstall, and localization friendly pieces. If you need to check the latest GetScreen.me details, look up the current docs online.
