AppCheck custom provider for non Firebase compatible (IoT, HarmonyOS, desktop, etc)

[Cătălin Florescu]

Hello,

I'm using Node.js library to generate and verify AppCheck tokens, but to generate is required AppId, id which is generated when adding a new app in console.

My question is how can I generate new tokens for unregistered apps (HarmonyOS phones, IoT devices, etc), since SDK allow to generate only if is passed an AppId. REST api requires the same, an AppId.

Thanks.
