I’m looking into developing an App Gallery extension that has similar features to the Link Hub app.
For example, I would like to be able to send a voice note. I don’t see any device control APIs in the standard App Gallery SDK, nor in the standard JS SDK.
Can you please help me understand what additional tools and SDKs are used in Link Hub to access device features? I’m assuming Link Hub is a full web app hosted on its own URL as opposed to a simple HTML5 app, but how is it developed? It seems to have features from the native SDKS, yet it is an App Gallery extension…?
Thanks!
