Harmony OS Huawei Watch 3 Pro

Hello guys !
I have been away for too long, I have a ton of request to update my faces for the OG Huawei Watch.
I upgraded my gear and I now wear a Huawei Watch 3 Pro, running Harmony OS, and I’d looove making faces for this baby too.
Will Facer be compatible on Harmony one day ?
Are there other methods ?

But I don’t understand what is “the tool provided by HarmonyOS”

PS : promise, I’ll power up my OG watch soon and update my faces :+1::+1:
