Looking for options for Price Checker for controller players

Hi,

I really like how PoE2 plays with a controller, but one thing I really miss is price checking items. The current overlays seem to only work with keyboard and mouse. So far I've ended up here:
1. Extending existing overlays: we can listen for "controller hotkeys". However, there are 2 problems with that: We don't have many "free" buttons and might accidentally trigger the overlay in normal gameplay. And the current overlays are written in Electron, which has limited "hotkey" functionality. Extending it would require a custom C plugin and a nodejs wrapper around it to push the events to electron, the same way its done for keyboard and mouse. And one final limitation: this still requires you to run the game on a PC.
2. Another option would be reacting to chat "commands". However, I'm not quite sure if this wouldn't break ToS and I couldn't find a way to read chat. The idea here would be to create a custom command that you would type in chat and link the item. Something like: "/pricecheck <item>" and that can either trigger the overlay or respond to you in chat. This option still requires a PC and custom software running, and GGG may not be very happy with it at all.
3. And the third option, and I'd love it if GGG allows it and provide APIs around that: What if we have a chat bot in game? Someone you can whisper and it can process whatever you've sent, and reply back. So you would do: "/whisper PriceChecker <item>" in chat, and it will respond back with a whisper to you. In thoery this doesn't even need the game running if GGG have APIs for that. But with the current setup it also feels like it may break ToS. And the best part is, this wouldn't require custom software running, but can be ran somewhere on a server, and even console players or cloud gaming players can use it.

Either way, I'm just brainstorming what would be possible for controller players. And if someone from GGG is open to discussion around this I would be really greatful.
