We used the Elgato SDK to build the plugin. It's quite straight forward to use, easy to test, and well documented! There's also a very helpful Maker community on Discord if you get stuck.
I would like to extend my gratitude to Elgato for their amazing Stream Deck product. It has provided an incredible platform for my plugin, enhancing the way users interact with their tools. Thank you for creating such a versatile and user-friendly device!
